Cannabis law in Ontario (2026)
Last reviewed: 9 October 2026
In short: Ontario sets the minimum age at 19 and a public possession limit of 30 g of dried cannabis (or equivalent). Up to four plants may be grown per residence, and cannabis is sold through a private retail model. Smoking and vaping are allowed in private residences and many outdoor public places, but not in the places the province lists. The Ontario Cannabis Store sells up to 30 g per transaction, and drivers aged 21 or under, novice and commercial drivers have zero tolerance for drugs.

- Smoking and vaping are allowed in private residences, many outdoor public places such as sidewalks and parks, and designated hotel rooms. They are not allowed in indoor common areas, enclosed public places, schools and areas within 20 m of them, playgrounds, restaurant and bar patios, and certain other places. Cannabis may not be consumed in a vehicle or boat that is being driven. Municipal bylaws, leases and employers may add limits.
