Message from the Commissioner, Royal Canadian Mounted Police
Commissioner
I am pleased to present the 2020-2021 National DNA Data Bank annual report and to acknowledge the incredible work of the National DNA Data Bank as it celebrates its 20th anniversary this year. This would have not been possible without 20 years of employee dedication as well as the support of numerous partners in government, law enforcement, forensic and justice communities who have continued working together to provide a safe community for all Canadians.
Since building the National DNA Data Bank from scratch 20 years ago, the National DNA Data Bank has continuously improved its operations and technology to ensure efficient processes are in place to better serve and protect Canadians. It now stores over half a million DNA profiles in the criminal indices, which have produced more than 73,000 matches to date and assisted law enforcement agencies in the identification of suspects and victims, link crime scenes, and solve active and cold cases.
In addition to the success of the National DNA Data Bank, the National Missing Persons DNA Program also continues to grow — it now contains over 1,200 profiles in its database. As partner agencies submit more biological samples and DNA profiles to the program, we can work together to offer much-needed closure to the families and friends of missing persons.
The feature article and success stories in this report highlight the daily accomplishments of the National DNA Data Bank. This is possible with the technology improvements made throughout the years to expand the DNA profile acceptance criteria, along with legislative changes that allow for the qualification of more designated offences, leading to the increase in size of the data base. I am confident that the National DNA Data Bank will continue to modernize, evolve and grow to meet the needs and expectations of all Canadians.
Congratulations on a remarkable 20 years!
Brenda Lucki
Commissioner

20 year anniversary
DNA evidence was used to support criminal investigations in Canada as early as 1989, but it was not until June 30, 2000 that a national index containing the DNA profiles of criminal offenders would be created.
The origins of the National DNA Data Bank started in 1995 when Parliament unanimously passed former Bill C-104, an Act to amend the Criminal Code and the Young Offenders Act (forensic DNA analysis). It amended the Criminal Code to allow a judge to issue a warrant authorizing a police officer to obtain a biological sample from a suspect for the purpose of forensic DNA analysis in a criminal investigation. Five years later, on June 30, 2000, the DNA Identification Act was enacted and the National DNA Data Bank program was launched.
When the National DNA Data Bank first started its operations, it had the slow and steady task of collecting DNA profiles for two separate indices: one for the genetic profiles of known convicted offenders and the other for the DNA profiles processed from crime scenes across the country. The larger each of these indices grows, the more value they provide to criminal investigations. By 2006, the National DNA Data Bank achieved a milestone of 100,000 convicted offender profiles, with close to 7,000 matches between crime scenes and convicted offenders.
The value and relevance of indexing DNA profiles in support of the law enforcement and criminal justice communities continues to evolve. A few years ago, the role of the National DNA Data Bank expanded when there was an amendment to the DNA Identification Act that allowed new indices to be created in support of humanitarian investigations involving missing persons and unidentified human remains.
Over the past 20 years, DNA technology and innovation has also evolved and shaped the way many investigations are conducted and used as a trusted form of identification in criminal proceedings.
| Then | Now |
|---|---|
| In 2000, the National DNA Data Bank was developing DNA profiles by examining 14 DNA markers. | Today the National DNA Data Bank is developing DNA profiles by examining 24 DNA markers. The amount of genetic information collected from an individual helps increase the discrimination power of each DNA profile. |
| In 2000, the National DNA Data Bank only accepted DNA profiles for two indices in support of criminal investigations. | Today the National DNA Data Bank can accept DNA profiles for seven indices in support of criminal and humanitarian investigations. |
| In 2000, approximately 50 offences qualified as designated offences for which the court could issue a DNA order. | After significant legislative changes in 2008, more than 350 offences now qualify as designated offences. This means that more DNA profiles from convicted offenders are collected and entered into the Convicted Offenders Index for a variety of offences, from less serious to more violent and serious offences. |
| At the beginning, it took more than three years to get 1,000 DNA matches. | Today 1,000 DNA matches are made on average every three months or less. |
| On November 10, 2000, the National DNA Data Bank made its first match between two crime scene profiles, effectively linking two criminal investigations and providing new leads. Less than one month later, the National DNA Data Bank made its first match between a convicted offender profile in the Convicted Offender Index and a crime scene profile collected from a murder investigation. | The National DNA Data Bank has produced more than 73,000 DNA matches between offender hitsFootnote 4 and forensic hitsFootnote 5. As the indices continue to grow, the number and frequency of DNA matches also increases. Today, the National DNA Data Bank stores over half a million DNA profiles. |
|
Within the first year, the National DNA Data Bank implemented:
|
Regular updates to software and technology over the years has allowed the National DNA Data Bank to process approximately 20,000 DNA submissions each year. Enhancements to the Combined DNA Index System has also resulted in more efficient search strategies and has reduced administrative time to review the DNA matches identified. |
| Until 2018, the National DNA Data Bank processed blood, buccal and hair sample types. | Today, the National DNA Data Bank can process a variety of sample types, including bone and personal effects. The National DNA Data Bank also provides Y chromosome and mitochondrial DNA analysis. |

The National DNA Data Bank
The National DNA Data Bank is a centralized collection of over half a million DNA profiles that helps investigators across the country solve a range of crimes. The main goals are simple:
- link crime scenes across jurisdictional boundaries
- help identify or eliminate suspects
- determine whether a serial offender has been involved in certain crimes
- assist investigators, coroners and medical examiners to find missing persons and identify human remains
On behalf of the Government of Canada, the Royal Canadian Mounted Police (RCMP) is the steward of the National DNA Data Bank, which operates for the benefit of Canada's entire law enforcement community.
The DNA Identification Act allows the National DNA Data Bank to maintain the following indices (databases):
- Convicted Offenders Index
- Crime Scene Index
- Victims Index
- Voluntary Donors Index)
- Missing Persons Index
- Relatives of Missing Persons Index
- Human Remains Index
The Convicted Offenders Index, Crime Scene Index, Victims Index and Voluntary Donors Index provide assistance to criminal investigations as follows:
- Comparing DNA profiles found at crime scenes against the DNA profiles of convicted offenders (Crime Scene Index to Convicted Offenders Index). When a match is made, it can help identify a suspect. An "offender hit" is the term used to describe this type of DNA match. If no match is made, this information can also help eliminate suspects.
- Comparing DNA profiles found at different crime scenes (Crime Scene Index to Crime Scene Index). When a match is made between DNA profiles found at separate crime scenes, it can help link crimes for which no suspects have been identified. This determines whether a serial offender is involved in a number of cases. A "forensic hit" is the term used to describe this type of DNA match.
- Comparing DNA profiles contained in the Victims Index and the Voluntary Donors Index. This helps to identify unknown victims, link crime scenes together through victim and voluntary donor DNA profiles, or eliminate the voluntary donors from the focus of an investigation. The Voluntary Donors Index can also be used for elimination purposes in humanitarian investigations.
As part of the National Missing Persons DNA Program, the National DNA Data Bank maintains the Missing Persons Index, Relatives of Missing Persons Index and Human Remains Index to support humanitarian investigations at the national level. These indices allow DNA profiles developed from biological samples and other items collected and submitted by police, coroners and medical examiners to be compared to other DNA profiles in the National DNA Data Bank. The DNA profiles in the Relatives of Missing Persons Index are only compared to those in the Missing Persons Index and the Human Remains Index.
Note
Since the creation of the National Missing Persons DNA Program, the National DNA Data Bank has reported 25 DNA associations that have assisted in the identification of unidentified human remains.
Offender and forensic hits
When the National DNA Data Bank first began operating in 2000, it contained few DNA profiles. As more DNA profiles are added to the National DNA Data Bank over the years, a greater number of matches are made in less time.

The decrease in numbers this reporting period is attributed to the global pandemic, which impacted the volume of submissions throughout 2020 and significantly disrupted partner contributions and the National DNA Data Bank's ability to provide services at full capacity.
Convicted offender submissions
Every year, the National DNA Data Bank processes convicted offender submissions consisting of:
- biological samples (used to generate DNA profiles that are entered into the Convicted Offenders Index); or
- Endorsement submissions (fingerprints and documentation for convicted offenders whose DNA profiles are already in the Convicted Offenders Index).
Before executing a new DNA order or authorization, a police officer must query the Canadian Police Information Centre to determine whether a convicted offender's DNA profile is already in the National DNA Data Bank. Endorsements therefore consist only of fingerprints and documentation. The endorsement process ensures that a convicted offender's DNA profile will remain in the National DNA Data Bank if the endorsement is received prior to:
- the conviction for which the original DNA order was made is being quashed on appeal;
- the original DNA order/authorization is being quashed on appeal; or
- the retention period is expiring because the person was either:
- convicted as a young person; or
- previously discharged under Section 730 of the Criminal Code of a designated offence. (Note: this condition was removed as of March 6, 2018 when amendments to the DNA Identification Act came into force).
When the National DNA Data Bank receives either a biological sample or an endorsement submission, the documentation is reviewed to ensure that the DNA order was issued for a criminal offence for which DNA can legally be collected and that the offender's personal information required for the submission is complete and accurate.
All convicted offender submissions are recorded in the National DNA Data Bank's internal tracking system without any of the offender's personal information. Documentation for convicted offender biological sample and endorsement submissions are sent to the RCMP's Canadian Criminal Real Time Identification Services so they can be certified; associated with an individual by fingerprint comparison; and recorded in the individual's criminal record.
Processing of biological samples
Convicted offender samples
When someone is found guilty of committing a designated offence for which a biological sample can be obtained, the judge has the choice to issue a DNA order. However, for some designated offences, such as murder, the judge must issue an order. A trained peace officer will then collect a biological sample from that person by taking a blood, buccal or hair sample. The National DNA Data Bank is responsible for processing all convicted offender biological samples and entering the DNA profiles derived from these samples into the Convicted Offenders Index.
Kits designed specifically for the National DNA Data Bank are used for collecting biological samples from offenders. There are three types of kits available:
- Blood: The sample is obtained by using a sterile lancet to prick the fingertip
- Buccal: The inside of the mouth is rubbed with a foam applicator to obtain skin cells
- Hair: Six to eight hairs are pulled out with the root sheath attached
Although all three types of biological samples have been legally approved for collection, more than 98% of samples taken from convicted offenders are blood samples. The National DNA Data Bank encourages the collection of blood samples because blood has proven to be more reliable than hair or buccal samples in generating high-quality DNA profiles.
Crime scene and victim samples
Crime scene DNA evidence is collected by police investigators and examined by forensic laboratories across Canada to generate DNA profiles. Only a DNA profile derived from a designated offence can be added to the National DNA Data Bank's Crime Scene Index or the Victims Index. The National DNA Data Bank is also responsible for removing victims' DNA profiles in accordance with the DNA Identification Act. The following public forensic laboratories are authorized to add DNA profiles to the Crime Scene Index and Victims Index:
- The RCMP National Forensic Laboratory Services in Ottawa, Edmonton and Surrey;
- The Centre of Forensic Sciences in Toronto and Sault Ste. Marie, Ontario; and
- The Laboratoire de sciences judiciaires et de médecine légale in Montréal, Quebec.
Voluntary donor samples
Samples collected from voluntary donors during the course of a criminal investigation of a designated offence are processed by a public forensic laboratory. If the resulting DNA profile provides a potential benefit to the investigation, it is added to the National DNA Data Bank's Voluntary Donors Index. Voluntary donor samples collected as part of a humanitarian investigation are provided to the National DNA Data Bank for processing and added to the Voluntary Donors Index. The National DNA Data Bank is responsible for removing voluntary donors' DNA profiles in accordance with the DNA Identification Act.
Missing persons, relatives of missing persons and human remains samples
Processing of samples from missing persons, relatives of missing persons and found human remains falls within the National Missing Persons DNA Program. This program is a partnership between the National Centre for Missing Persons and Unidentified Remains and the National DNA Data Bank. The role of the National Centre for Missing Persons and Unidentified Remains is to act as a single point of contact for investigators. As such, the National Centre for Missing Persons and Unidentified Remains authorizes the submissions to the National DNA Data Bank for missing persons and human remains investigations.
Under the DNA Identification Act, the National DNA Data Bank is responsible for maintaining the humanitarian indices and also for:
- receiving biological samples from submitting agencies and developing DNA profiles;
- receiving DNA profiles from approved laboratories for technical review;
- interpreting and comparing DNA profiles from human remains, relatives of missing persons and personal belongings from missing persons;
- adding and removing DNA profiles in the Human Remains Index, Relatives of Missing Persons Index and Missing Persons Index in accordance with the legislation;
- issuing and explaining kinship and identity association reports; and
- providing scientific advice and support to the National Centre for Missing Persons and Unidentified Remains and investigators, as required.
To better serve the National Missing Persons DNA Program, the National DNA Data Bank introduced technologies for the isolation and characterization of DNA. Specifically, it introduced procedures for the development of DNA profiles from personal effects and hard tissue samples, such as bone and teeth. In addition, the National DNA Data Bank validated procedures to analyze the Y-chromosome and utilize an advanced technology using Next Generation Sequencing, which allows for mitochondrial DNA analysis.

Comparing DNA profiles
The DNA profiles in the National DNA Data Bank are compared using the Combined DNA Index System, which is a secure network and software program developed by the Federal Bureau of Investigation and the United States Department of Justice, and provided to the RCMP for use by the National DNA Data Bank. Combined DNA Index System has become an internationally accepted tool for many forensic laboratories, allowing DNA profile information to be compared using a standard, secure format. In Canada, the National DNA Data Bank uses Combined DNA Index System for daily comparisons of DNA profiles. Each new DNA profile entered into one of the National DNA Data Bank's DNA indices is automatically compared against all existing profiles contained in other DNA indices as permitted by the DNA Identification Act.
International participation
The National DNA Data Bank shares DNA information with international investigating authorities through an international DNA Information Sharing Agreement with INTERPOL. This agreement is approved by the Government of Canada and is limited to investigations and prosecutions of designated offences or investigations involving missing persons and unidentified human remains.
Since the first international agreement was signed in 2002, the National DNA Data Bank has received 1,889 incoming international requests related to criminal investigations to search the Convicted Offenders Index (COI), the Crime Scene Index (CSI), the Missing Persons Index (MPI) and the Human Remains Index (HRI). These searches produced 7 offender hits and 11 forensic hits. Furthermore, the National DNA Data Bank has sent 353 requests related to criminal investigations to other INTERPOL countries for comparison to DNA profiles developed from crime scene samples, resulting in 8 offender hits and 2 forensic hits.
In 2018, the agreement was updated to allow international comparisons of DNA profiles from missing persons and unidentified human remains. Since then, the National DNA Data Bank has received 89 incoming international requests to search missing persons and unidentified human remains profiles against the Convicted Offenders Index, the Crime Scene Index, the Missing Persons Index and the Human Remains Index. The National DNA Data Bank has sent 26 requests to other INTERPOL countries for comparison of DNA profiles developed from missing persons and unidentified human remains. To date, none of these searches have resulted in an association.
Privacy of information
The DNA Identification Act specifies that DNA profiles in the National DNA Data Bank's indices can only be used for law enforcement or humanitarian purposes. The Act also clearly states that the DNA profiles in the Relatives of Missing Persons Index can only be compared to DNA profiles in the Missing Persons Index and Human Remains Index.
As an additional safeguard to protect the privacy of an individual, when a convicted offender's DNA sample arrives at the National DNA Data Bank, the donor's identity is separated from his or her genetic information, and the sample is identified by a numeric bar code. These bar codes are the only link connecting personal information, the biological sample and the DNA profile. The offender's personal information is kept in a separate registry maintained by the RCMP's Canadian Criminal Real Time Identification Services, which National DNA Data Bank employees cannot access. This process ensures that National DNA Data Bank staff never know which convicted offender's DNA profile they are processing. Likewise, Canadian Criminal Real Time Identification Services employees do not have access to the genetic information of an offender. With the exception of biological sex, DNA profiles held within the indices of the National DNA Data Bank do not reveal any medical or physical information about the donor.
The Act further protects Canadians' privacy rights by requiring informed consent for submissions to the Relatives of Missing Persons Index, the Victims Index and the Voluntary Donors Index. This consent can be withdrawn at any time by the contributor. In addition, at least once every five years, the investigating agency is contacted about the case to ensure that the person from whom the DNA profile was obtained has not withdrawn their consent. Investigators are also asked whether they believe the DNA profile will continue to assist in the investigation for which it was obtained. If removal is requested or if the investigating agency fails to respond, then the DNA profile is removed from the appropriate DNA index and the biological sample is destroyed.
Lastly, the National DNA Data Bank will only share DNA information with other investigative authorities as permitted by legislation.
The value of secondary designated offence submissions
The Criminal Code classifies those offences that may be the subject of a DNA order as either primary or secondary designated offences. When the National DNA Data Bank first started its operations in 2000, the number of secondary designated offences was limited. In 2008, the Criminal Code was amended and the list of secondary designated offences was expanded to include a wider range of offences (for example failure to appear and drug offences). While usually less violent, these offences can help solve more serious criminal offences.
To illustrate the value of these offences, offender hit data was selected from the National DNA Data Bank for a few common secondary designated offences. The figure below provides the number of offender hits to ongoing investigations (including murders and sexual assaults) that were the outcome of DNA orders being issued for offenders convicted of secondary designated offences.

Process for reporting a DNA match: Criminal investigations
- National DNA Data Bank processes biological samples from convicted offenders and enters the resulting DNA profiles into the Convicted Offenders Index
- National DNA Data Bank runs a search between the Crime Scene Index and the Convicted Offenders list
- DNA match between a convicted offender's DNA profile and a crime scene DNA profile
- The offender, the crime scene and the laboratory identifiers are brought to the Canadian Police Services Information Centre (CPSIC)
- CPSIC forwards the convicted offender data to the forensic laboratory
- Forensic laboratory passes the convicted offender identity information to the investigator
- Forensic laboratories process biological samples left at crime scenes and enter the resulting DNA profiles into the Crime Scene Index
- National DNA Data Bank runs a search between the Crime Scene Index and the Convicted Offenders list
- DNA match between a convicted offender's DNA profile and a crime scene DNA profile
- The offender, the crime scene and the laboratory identifiers are brought to the Canadian Police Services Information Centre (CPSIC)
- CPSIC forwards the convicted offender data to the forensic laboratory
- Forensic laboratory passes the convicted offender identity information to the investigator
Process for confirming a DNA match: Criminal investigations
- The investigator assesses the case evidence to determine if further investigation of the suspect is required
- If evidence of a match between the convicted offender and the crime scene DNA profiles is required for court purposes, the investigator must apply to a provincial court judge for a DNA warrant; if the DNA warrant is ordered, a biological sample can be collected from the suspect under that authority
- The biological sample is submitted to a forensic laboratory for analysis where the forensic laboratory compares the suspect's DNA profile to that of the crime scene evidence
- The forensic laboratory issues a report confirming a DNA match between the suspect's DNA profile and that of the crime scene evidence
- Based on the laboratory report and other investigative information, the investigator can consider whether charges should be laid or recommended against the suspect
Success stories
For the past 20 years, the National DNA Data Bank has provided vital support to over 73,000 criminal investigations and court proceedings at the local, national and international levels. The index of convicted offenders DNA profiles has been crucial in helping to solve numerous cold cases. Some of the more high profile of these investigations include the sexual assault and brutal murder in 1984 of a popular Quebec actress, Denise Morelle; the 1992 murder of Marie Lorraine Dupe, a convenience store clerk in Nova Scotia who was stabbed repeatedly; the 1987 murder of Lilian Berube who was beaten to death during a break and enter; the 1995 attempted murder of a Quebec correctional officer; and the violent murders of two children in two separate cases, six-year-old Corrine Gustavson in Alberta in 1992 and nine-year-old Joleil Campeau in Quebec in 1995. The offenders left behind no leads other than DNA and it was this that eventually helped identify them and link them to their heinous crimes.
In other cases, quick identification was possible because the offender's DNA was already in the National DNA Data Bank. This was the case in 2016 when a suspect was arrested six days after the sexual assault of a young woman on New Year's Day in Newmarket and in the case of 2 sexual assaults in Montréal in 2018 where the serial offender was identified within a few weeks. The National DNA Data Bank has also provided valuable information across Canada's borders. One example is in 2002, a disturbing Ohio murder where the suspect was identified as a known offender in Canada following the airing of an episode of America's Most Wanted.
All these and countless other cases have been supported by the National DNA Data Bank in accordance with the DNA Identification Act. A few other stories are provided here in more detail and have been randomly selected to help showcase the value of DNA databases in support of public safety. Due to cases still being in the courts and other considerations, the following true stories represent only a sample of the numerous cases where DNA analysis has been instrumental in shaping the course of an investigation.
Calgary hit and run
In August 2018, a Calgary police officer responded to a call about a suspicious vehicle. As the officer approached the vehicle, he was knocked down and run over as the driver fled the scene. The officer suffered multiple serious injuries requiring surgery, and spent four days in the intensive care unit on a ventilator.
The suspect's vehicle had been stolen and was found abandoned later that day in another part of the city. Police collected fingerprints and DNA from the vehicle. This case was given high priority by the RCMP National Forensic Laboratory to conduct DNA analysis and one week after the incident, a DNA match was made with a convicted offender in the National DNA Data Bank. Fingerprints were also used to identify and link the individual to the stolen car.
On the first day of his trial, the offender pled guilty to criminal negligence causing bodily harm and failure to stop at an accident. He was given a five-year sentence and was prohibited from driving for seven years.
The laboratory was able to assist with this urgent request and provided a profile for the offender in a very short period of time. The DNA profile provided key evidence in identifying the offender and placing him in the vehicle.
DNA helps catch a violent offender
In August 2018 in southern Ontario, a woman was violently sexually assaulted. After the assault, her assailant told her that he was going to kill her and chop her up. She believed him because the area where she had been assaulted was covered in plastic. The man had her forcibly pinned down but as he was getting dressed, she managed to escape and call 911 from a nearby pay phone while her aggressor left the scene.
Laboratory examination and analysis of samples collected from the victim's body led to the development of a suspect profile, but there was no hit in the National DNA Data Bank at the time. Police searched the area and analyzed video footage from the scene. The one viable suspect was eliminated by a photo line-up and the investigation soon stalled.
Three months later, a hit between the suspect DNA profile found on the victim to an individual who had been recently convicted of a secondary designated offence was reported. The assailant was arrested and charged in December 2018. In May 2020, he was convicted for sexual assault and is scheduled to be deported once his sentence is served.
The accused was not a person of interest and he was living outside the city at the time of the incident. Had it not been for the DNA match, it is unlikely that this violent sexual assault would have been solved.
Needed a fix
In 2003, Laval police began investigating a string of home break and enters. In each case, the suspect entered through either the patio door or a back window and left behind something that could be used to develop a DNA profile. Sometimes it was blood recovered from the broken window, other times it was a clothing item, such as a tuque, gloves or jacket. The DNA profile from each crime scene matched to the same individual, linking over 19 break and enter incidents over the 13 years, but the identity of the individual remained unknown.
In December 2016, police received a 911 call. The caller said she was witnessing someone break into her neighbours' house while they were away. She kept the 911 operator on the phone as she followed the suspect after he left the house. The man was arrested for the break and enter. Upon conviction for that single offence, a DNA order was issued and a biological sample was submitted to the National DNA Data Bank. It is important to note that in 2008, the legislation changed mandating a DNA order upon conviction of break and entering a residential house. The DNA profile developed from this convicted offender matched the DNA profile obtained from the 19 previous unsolved break and enter cases. It was later discovered that the individual was addicted to drugs and was breaking into homes to get money to feed his habit.
What's interesting is that some of the files dated back more than a decade. DNA had been collected at the time and linked to the other cases, but the individual remained unknown. Once the suspect's DNA profile was fed into the Convicted Offenders Index, we were able to solve all of them.
Sweater and blueberries
In the afternoon of July 30, 2013, an employee of a roadside blueberry business in the area of Sudbury was robbed by an armed suspect. The suspect used a hammer to threaten the employee and then fled the scene on foot. Shortly after, the police canine unit found a discarded sweater nearby. The employee identified the sweater as the one worn by the suspect who had threatened her with bodily injury and robbed her. Later, the victim could not identify the suspect in a photo line up, making the physical evidence collected at the scene even more critical.
Biological samples were taken from the sweater and a DNA profile for an unknown male was generated and entered into the National DNA Data Bank; no match was returned. Officers exhausted all other possible leads but the suspect remained unknown and at large. There was an increased risk to public safety as the suspect committed the robbery in broad daylight and had a propensity towards violence.
Two years after the robbery, the National DNA Data Bank got a hit. A biological sample had been taken from an individual and submitted to the National DNA Data Bank for a recent conviction. When his DNA profile was entered into the convicted offender's index, it matched the DNA profile from the suspect involved in the armed robbery. The offender was convicted of robbery and received a 20-month sentence. No matter where the crime takes place, the National DNA Data Bank provides highly specialized services to all law enforcement agencies across the country for any designated offence investigation.
This investigation was ongoing for several years. Without the assistance of the National DNA Data Bank this investigation would have remained unsolved.
Justice for a child victim
In 2006, in Ottawa, a teenage girl was sexually assaulted while she was out walking. The girl was alone and frightened but bravely fought off her attacker, scratching him on the face. She managed to escape and went to police where biological material from her attacker was taken from her fingernails. A DNA profile of an unknown male was generated and added to the National DNA Data Bank. Unfortunately, without a DNA match to a known offender and no other leads, the case remained unsolved for the next 13 years.
In 2019, a man was convicted of voyeurism, a secondary designated offence. Once his DNA profile was added to the National DNA Data Bank, it matched the profile of the unknown male from the attack on the young girl back in 2006. Faced with the evidence, the man pled guilty in May 2020 to the 2006 sexual assault and is currently serving his sentence.
The victim in this case said that her faith in the criminal justice system was renewed when her case was finally solved after all these years. The fact that it was DNA that led to the identification, arrest and eventual conviction of the offender gave the victim confidence that the police had the right suspect.
Victims in historical cases often express a huge weight has been lifted and they finally have closure when the offender is brought to justice. I suspect there are likely many unsolved cases that will be solved as DNA testing improves. This is a very good thing for the victims who seek, and still don't have, the closure they need to deal with the trauma of the offence and try to move on with their lives.

Biological samples received versus DNA profiles contained in the Convicted Offenders Index: As of March 31, 2021, the National DNA Data Bank received 456,810 biological samples, of which 411,999 DNA profiles were contained in the Convicted Offenders Index. The difference of 9.8 % can be attributed to rejected samples, duplicate samples, biological samples in the process of being analyzed and DNA profiles removed from the Convicted Offenders Index because of an absolute or conditional discharge, expired retention period, or because the conviction or the DNA order/authorization was quashed on appeal.

Note
The above information represents the convicted offender submissions received and is not reflective of the number of convictions eligible for a DNA order.
Retroactive authorizations
This is a biological sample taken from an offender who was found guilty of certain designated Criminal Code offences before June 30, 2000. The authorization is granted as per qualifying criteria set out in s.487.055 of the Criminal Code. Under this provision, the National DNA Data Bank has received 5,035 submissions.
Rejection of National DNA Data Bank submissions
The National DNA Data Bank has rejected only 6,986 (1.5%) of the biological samples and 2,786 (1.5%) of the endorsements it has received to date. Reasons for rejection include: the offender was convicted of a non-designated offence, the biological sample was inadequate, the collection kit used was inappropriate (sample), the offender's DNA profile was not contained in the Convicted Offenders Index (endorsement), or the DNA order was missing or invalid.
Collection of additinal bodily substances
If a biological sample is rejected because the quality of the sample is deemed inadequate for DNA analysis, or if it was not submitted in accordance with the DNA Identification Regulations, an application for resampling can be authorized by a judge. Since June 30, 2000, the National DNA Data Bank has received 1,830 samples taken under this provision.
