Ontario Cannabis Laws for Adults and Visitors: Age, Public Limit and Retail
Educational summary, not legal advice. This is a short overview, not a complete statement of provincial or federal law. Ontario's own linked page and statute were indexed through official search but returned 403 on direct browser opens; they are not used as verified support here.
Three Ontario basics to check
Health Canada's directly readable province and territory directory lists Ontario's legal age for adult-use cannabis as 19. The same entry gives a public possession limit of 30 grams of dried cannabis or equivalent. The directory also links Ontario's authorized retail channels: private licensed in-person stores and a government-operated online store. Follow its Ontario store links to check current authorization rather than relying on a seller's own claim.
These are selected basics, not a full guide to where cannabis may be used, home cultivation, medical access, workplace rules, impaired driving, or travel. Those topics can involve separate rules; this page does not answer them. A visitor should check the rules that apply in Ontario instead of assuming another province's rules carry over.
How to check a retailer
Health Canada says legal products are sold through retailers authorized by provincial or territorial governments, and its Ontario entry links to the relevant retail channels. The same federal page flags warning signs of illegal retailers, including no age verification and a seller that claims to ship cannabis everywhere in Canada. Treat those as reasons to verify, not as a complete test of legality.
