Background
Chien Vu, a first-time offender, pleaded guilty to one count of assault after a dispute with his neighbour over the state of the neighbour’s lawn. The neighbour suffered a laceration to the chin requiring stitches and bruising near his eyebrow. The Ontario Court of Justice sentenced Vu to a conditional discharge with 18 months’ probation and also ordered him to provide bodily substances for forensic DNA analysis under the DNA Identification Act. Because Vu received a conditional discharge rather than a conviction, a successful completion of probation would mean no criminal conviction would register on his record.
Vu appealed the DNA order to the Superior Court of Justice. The summary conviction appeal judge (SCAJ) allowed the appeal and set aside the DNA order. The SCAJ found that the sentencing judge had failed to account for a legally significant disparity: under the DNA Identification Act, a convicted offender who later obtains a record suspension has their stored DNA sample sequestered and rendered unavailable for further forensic analysis under s. 10(8) of the Act, whereas a discharged offender — ineligible for a record suspension — enjoys no such protection. The discharged offender’s DNA sample can remain in the national DNA data bank indefinitely, subject only to the RCMP Commissioner’s discretionary power to destroy it under s. 10(6).
The Crown was granted leave to appeal to the Court of Appeal for Ontario, arguing that the SCAJ had misread the Act and had improperly focused on privacy to the exclusion of all other mandatory sentencing factors under s. 487.051(3) of the Criminal Code.
The Court’s Holding
The Court of Appeal unanimously dismissed the Crown’s appeal. Writing for the panel of Zarnett, George, and Copeland JJ.A., Justice George held that the SCAJ had correctly identified a meaningful legislative gap: a convicted offender who obtains a record suspension benefits from s. 10(8) of the DNA Identification Act, which sequesters the physical DNA sample, bars its use for any further forensic analysis, and prohibits disclosure of its very existence. A discharged offender, by contrast, is not “a person who has been convicted” within the meaning of s. 3(1) of the Criminal Records Act and therefore cannot apply for a record suspension. As a result, the discharged offender’s DNA sample remains available in the national DNA data bank and could be subjected to new or yet-to-be-developed testing methods in perpetuity, subject only to the Commissioner’s discretionary destruction power under s. 10(6).
The court rejected the Crown’s argument that this distinction is inconsequential because DNA profiles (the analytical end-product) are retained indefinitely for both categories of offender. Justice George explained that a DNA sample and a DNA profile are not equivalent: the physical sample contains the entirety of an individual’s genome — capable of revealing intimate biological information — whereas a profile reflects only a narrow subset of gene sequences used for identification. Retaining the sample thus preserves the state’s ability to conduct future, more invasive analyses in a way that retaining only the profile does not.
The court also rejected the Crown’s second ground — that the SCAJ had failed to weigh all mandatory factors under s. 487.051(3) of the Criminal Code. Reading the SCAJ’s reasons as a whole, the court found he had accepted the sentencing judge’s assessment of those factors and appropriately focused on the one element she had overlooked: the heightened privacy impact arising from the Act’s differential treatment of discharged versus convicted offenders. That differential treatment was directly relevant to the “impact on privacy and security” factor mandated by s. 487.051(3), and the sentencing judge’s unawareness of it justified appellate intervention.
Key Takeaways
- When sentencing a discharged offender for a secondary designated offence, a court must specifically consider that the offender cannot obtain a record suspension and therefore cannot benefit from the s. 10(8) protection that sequesters DNA samples — a gap the sentencing judge failed to appreciate here.
- There is a legally meaningful distinction between a DNA sample (the raw biological material, retestable with future technology) and a DNA profile (the analytical result of a specific test). Privacy interests in the two are not co-extensive, and the Act treats them differently for offenders who obtain record suspensions.
- Discharged offenders whose DNA samples are ordered into the national data bank have no guaranteed path to removal; their only recourse is the RCMP Commissioner’s discretionary destruction power under s. 10(6), an administrative remedy the SCAJ found it inappropriate to impose on a discharged first-time offender.
- The 2018 amendments to the DNA Identification Act that repealed ss. 9(2)(c) and 10(7)(c) — which had previously provided for automatic removal of discharged offenders’ DNA data and destruction of their samples — created the legislative lacuna at the heart of this case.
Why It Matters
This decision clarifies that sentencing judges in Ontario must grapple with the DNA Identification Act‘s post-2018 architecture when considering DNA orders for offenders who receive discharges. The ruling makes explicit what the Act’s text leaves implicit: the 2018 repeal of the automatic destruction and removal provisions for discharged offenders inadvertently created a harsher DNA-retention regime for those who receive the more lenient sentencing outcome of a discharge, compared to those who are convicted and later obtain a record suspension. Practitioners and judges must now weigh this asymmetry as part of the privacy-impact analysis under s. 487.051(3) of the Criminal Code.
The case also reinforces broader principles about DNA evidence and privacy. Citing the Supreme Court of Canada’s reasoning in R. v. R.C., 2005 SCC 61, the court underscored that DNA samples are among the most intimate data the state can hold — capable of disclosing biological information well beyond what any current test reveals — and that privacy interests in retained samples must be assessed with that potential in mind, not merely in light of what has already been extracted from them.
