Cannabis legal age and possession limits by province and territory

Last reviewed October 25, 2026 · Based on official government sources

The minimum age to buy, have or use non-medical cannabis is set by each province and territory, and the federal law sets a national limit on how much an adult can carry in public. Some provinces add their own limits on purchases, home possession or home growing. This guide puts those numbers in one place, using official sources only.

Minimum age

According to Health Canada’s table of provincial and territorial rules:

18: Alberta.
19: British Columbia, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, Yukon, Northwest Territories and Nunavut.
21: Quebec.

The age that applies is the one where you are, not where you live. A 19-year-old from Ontario visiting Quebec cannot legally buy or have cannabis there, and Quebec’s law says people under 21 may not be admitted into a cannabis store. Giving or selling cannabis to someone under the legal age is an offence everywhere in Canada.

The 30 gram public possession limit

Every province and territory limits adults to having 30 grams of dried cannabis, or the equivalent, in public. Health Canada’s possession calculator sets out the equivalents. One gram of dried cannabis equals:

5 grams of fresh cannabis;
15 grams of edible product (solid);
70 grams of liquid product (non-solid);
0.25 grams of concentrates (solid or liquid);
1 cannabis plant seed.

If you have more than one type of product with you, the amounts add up. The calculator on Health Canada’s website does the maths for you.

Purchase limits

Several provinces limit how much can be sold in a single purchase. Examples from official sources:

Ontario: up to 30 grams at a time.
British Columbia: up to 30 grams per transaction.
Alberta: orders may not exceed 30 grams of dried cannabis or equivalent; more than one purchase can be made, but you still cannot have more than 30 grams in public.
Quebec: no more than the equivalent of 30 grams per visit to the SQDC.
Manitoba: retailers may sell up to 30 grams of dried cannabis or equivalent, or up to four plants, to an individual.

Possession at home

Federal law does not set a limit on how much cannabis an adult can keep at home, but some provinces do:

Quebec: 150 grams of dried cannabis or equivalent per residence, no matter how many adults live there.
British Columbia: 1,000 grams per household.
Nova Scotia and Prince Edward Island say there is no limit on the amount kept at home for personal use.

Several provinces also require cannabis at home to be stored so that young people cannot get at it. New Brunswick’s law, for example, requires it to be kept in a secure space that a person under 19 cannot access. See safe storage around kids and pets.

Growing at home

Federally, adults may grow up to four plants per household (not per person) from legal seeds or plants, subject to provincial and local rules. Rules vary:

Quebec prohibits growing cannabis for personal use and having a cannabis plant.
Manitoba has allowed adults 19 and older to grow up to four plants per household since May 1, 2025, indoors and out of reach of young people.
Newfoundland and Labrador allows four plants per dwelling, grown indoors or in a secure building such as a shed; growing outdoors is not permitted.
Landlords and condominium boards can restrict growing in many provinces.

Sharing

Health Canada says adults may share up to 30 grams of legal dried cannabis or equivalent with other adults, but may not sell it. Sharing with anyone under the legal age is illegal.

Youth possession

Provinces set their own penalties for young people who have cannabis. Saskatchewan, for example, says possession of less than five grams by a minor is a provincial offence that can lead to a fine, while possession of more than five grams can lead to criminal prosecution under the Youth Criminal Justice Act. Nova Scotia describes a similar structure. This site is for adults of legal age only.
