Cannabis Road Safety Laws

Every year, there are tens of thousands of impaired driving incidents in Canada, including several thousand drug-impaired driving incidents.

Canadian legislation prohibits driving while impaired by alcohol, cannabis or a combination of both. Impaired driving is a serious crime that can threaten both your and your loved ones’ safety and that of others on the road. CAA has compiled information you need to know about cannabis and impaired driving in Canada.

Cannabis regulation varies between jurisdictions. This Government of Canada tool shares links to all provincial and territorial legislation, with a brief breakdown of the regulations.
