Buying seeds is legal in Canada, but only from the right sources and only if you are of legal age. Here is where seeds can come from, how they count against your limit, and the difference between regular, feminized and autoflowering seeds.
Is it legal to buy weed seeds in Canada?
Yes, for adults. The Cannabis Act allows you to buy cannabis seeds from a federally licensed seller or from a retailer authorized by your province. You must be at least the legal age where you live, which is 18 in Alberta, 21 in Quebec and 19 in the rest of the country.
Legal seeds exist so that people who are allowed to grow can start from a known, regulated source. The home-grow limit is four plants per residence, and some provinces restrict it further. Quebec bans home growing entirely. See growing weed in Canada for the rules by province.
Buying seeds is not the same as being allowed to plant them. In Quebec, for example, a seed purchase does not change the ban on growing.
Where can you legally get weed seeds in Canada?
There are two legal routes: a federally licensed seller, and a provincially authorized retailer. Provincial rules decide what the second route looks like. In Ontario, seeds and seedlings must come from the Ontario Cannabis Store or an authorized store. In Manitoba, they must come from a licensed Manitoba store. British Columbia points buyers to licensed stores and BC Cannabis Stores.
Not every retailer carries seeds, and the range depends on what licensed producers supply. If a store does not list them, that is a stocking choice and not a legal barrier.
A seed bought from an unlicensed source, or imported from outside Canada, is not a legal seed. Importing cannabis seeds without a permit is an offence, and border officers can seize them. Keep your receipt and the packaging, because they show where the seeds came from.
Do seeds count toward the 30 g limit?
Yes. Under Schedule 3 of the Cannabis Act, one cannabis plant seed counts as 1 g of dried cannabis. The public possession limit is 30 g of dried cannabis or the equivalent, so an adult carrying only seeds could have up to 30 of them.
The limit is combined across forms. If you are carrying 20 g of dried flower, you could have at most 10 seeds on top. Our weed measurements guide shows the full equivalency table for edibles, concentrates and beverages.
The 30 g cap applies to carrying in public. What you keep at home is governed by provincial rules, and several provinces set no limit on legally bought cannabis at home. Plants, though, are always limited to four per residence.
| Form | Counts as 1 g of dried cannabis | Equals the 30 g limit at |
|---|---|---|
| Dried cannabis | 1 g | 30 g |
| Cannabis plant seeds | 1 seed | 30 seeds |
What is the difference between regular, feminized and autoflower seeds?
Regular seeds grow into a roughly even mix of male and female plants. Only females produce the flowers that are smoked, vaped or used in edibles, and a male can pollinate nearby females and fill their flowers with seeds. Growers sort the sexes early and remove the males. Our guide to male vs female weed plants explains how.
Feminized seeds are bred so nearly all plants are female. Because home growers are capped at four plants, many choose feminized seeds to avoid losing plants to males. Feminized does not mean a different strain, only a different seed type.
Autoflowering seeds flower after a set number of weeks, not in response to a change in light. They are often smaller and quicker, which suits small spaces. They can also be feminized. See autoflower strains for the details.
How should you store and plant legal seeds?
Keep seeds in a cool, dry, dark place in their original package until you are ready to plant. Heat and damp are what ruin them, and a sealed package from a legal seller is already the right container. Seeds that have been stored well can stay usable for a long time, though germination rates fall as they age.
Plan the grow before you buy. Count your four plants, decide whether you have the indoor space or the out-of-sight outdoor spot your province requires, and check your lease. If you want to start more seeds than you can keep, remember that every seedling counts as a plant against the limit of four per residence.
Keep seeds and young plants away from children and pets. In several provinces the law expressly requires growing spaces to be inaccessible to anyone under the legal age.
What are the penalties for illegal seeds?
Penalties depend on what happened.
Possessing more than the public limit, or growing more than four plants at a residence, is treated much more seriously. Provinces also add their own fines, such as the fine range in Quebec of $250 and up for a plant at home.
If you are unsure whether a seed source is legal, the question to ask is whether the seller is federally licensed or provincially authorized. If you cannot answer yes, skip it.
