Quick Answer
Yes, from a seller your province authorizes. The Cannabis Act, in force since October 17, 2018, made Canada the second country in the world (after Uruguay) to legalize recreational cannabis nationwide. Adults of legal age can possess up to 30 grams of dried cannabis in public and buy cannabis online from their province’s authorized online store or licensed retailers. Unlicensed mail-order dispensaries are not part of that legal system.
Key Takeaways

- The legal age is 18 in Alberta, 21 in Quebec, and 19 in every other province and territory.
- Adults may possess up to 30 grams of dried cannabis (or equivalent) in public.
- Most provinces allow adults to grow up to 4 plants per household (Quebec and Manitoba restrict home growing).
- Each province regulates how cannabis is sold, both in stores and online.
What Does the Cannabis Act Allow?
The Cannabis Act sets the national framework: adults can legally possess and share up to 30 g, and buy cannabis from sellers their province authorizes, and Health Canada licenses producers and regulates product standards such as the 10 mg THC cap per package on regulated edibles. Provinces control distribution, retail models and minimum age.
What Is the Legal Age to Buy Weed in Each Province?
| Province/Territory | Legal Age |
|---|---|
| Alberta | 18 |
| Quebec | 21 |
| BC, Ontario, Manitoba, Saskatchewan, Nova Scotia, New Brunswick, PEI, Newfoundland, Yukon, NWT, Nunavut | 19 |
How Much Cannabis Can You Legally Possess?
Adults can carry up to 30 grams of dried cannabis in public, and section 8(1)(b) of the Act separately prohibits possessing any cannabis you know is illicit. Equivalency rules apply to other formats: 30 g dried equals roughly 150 g of fresh cannabis, 450 g of edibles, or 2,100 g of liquid product under the Act’s schedule.
Can You Legally Order Weed Online?
Yes, from an authorized seller. Legal online sales run through your province’s government online store or private retailers the province has licensed; in Ontario, for example, that is the Ontario Cannabis Store. Mail-order dispensaries that ship across the country, including Bud Cargo, are not provincially licensed retailers. The Cannabis Act defines cannabis sold by someone not authorized under federal or provincial law as illicit cannabis, and section 8(1)(b) prohibits adults from possessing cannabis they know is illicit. Learn how the process works in our guide to buying weed online in Canada.
What Are the Rules on Travelling With Cannabis?
You can travel between provinces with up to 30 g of legal cannabis, but taking cannabis across Canada’s international border — in either direction — remains a criminal offence, even to jurisdictions where cannabis is legal. Our guide to flying with weed in Canada covers carry-on and checked-bag rules, vapes, edibles and the Schedule 3 equivalents.
