The appellant challenged the Quebec Court of Appeal's opinion that ss. 1 to 7 of the Genetic Non-Discrimination Act, S.C. 2017, c. 3, exceeded Parliament's criminal law power under s. 91(27) of the Constitution Act, 1867.
The majority held that the pith and substance of the impugned provisions — prohibiting compelled genetic testing and non-consensual use or disclosure of genetic test results in connection with contracting and the provision of goods and services — was a valid exercise of the criminal law power, as the provisions respond to a reasoned apprehension of harm to autonomy, privacy, equality, and public health.
A concurring minority agreed on the result but characterized the pith and substance more narrowly as protecting health by giving individuals control over the intimate information revealed by genetic testing.
The dissent would have dismissed the appeal on the basis that the impugned provisions lacked a well-defined threat and adequate evidentiary foundation to constitute a valid criminal law purpose, falling instead within provincial jurisdiction over property and civil rights under s. 92(13).
