In Canada, the federal public possession limit is 30 grams of dried cannabis or its dried equivalent, and most licensed retailers cap a single order at that same number. Provinces and stores can set lower caps, and some count them per day rather than per transaction. The limit you actually hit at checkout is the smaller of the two.

What the Federal Limit Covers
Health Canada sets one baseline number for public possession: 30 grams of dried cannabis or its equivalent across other product types. It applies outdoors, in a vehicle, and at the pickup counter, no matter where the product came from. At home you may store more than 30 grams if it was legally purchased, and a household may grow up to four plants. Provincial rules can lower any of those numbers, so the federal figure works as a ceiling, not a promise.

Why the Retailer Cap Decides Your Cart
Provincial wholesalers and licensed retailers choose how much they will sell in one go. Most settle on the 30 gram equivalent because it keeps a customer inside the possession limit on the way home. The differences show up in the details: caps counted per order, per day, or per rolling period; separate caps for online and in-store; and hard stops at checkout that remove items from the cart instead of warning you.
That is where convenience enters the decision. When every retailer sells under the same 30 gram ceiling, speed of fulfillment, delivery windows, and pickup options become the real differentiators.

The Dried Equivalent Math
Edibles, beverages, and concentrates do not count gram for gram. Health Canada converts them back to dried cannabis:
- 1 gram of dried cannabis
- 5 grams of fresh cannabis
- 15 grams of edible product
- 70 grams of liquid product, such as beverages and oils
- 0.25 grams of concentrate, which is 1 gram of concentrate for every 4 grams of dried cannabis
A 30 gram cap therefore equals about 150 grams of fresh cannabis, 450 grams of edibles, 2,100 grams of liquid, or 7.5 grams of concentrates. Mix the categories in one order and the totals pool, so a few vape cartridges can use a large share of the allowance.
Provincial and Local Differences to Expect
- Minimum age ranges from 18 to 21 depending on the province.
- Some provinces also limit how much a person may keep at home.
- Delivery may be restricted by region or by time of day.
- Local bylaws can add rules on storefronts and delivery zones.
Check the province where the order ships to, not the province you happen to be standing in.
How to Plan an Order That Clears Checkout
- List what you want and convert each item to its dried equivalent before adding it to the cart.
- Add the converted numbers. If the total passes 30, remove something instead of waiting for the checkout error.
- Read the store's own limit and look for wording about per order, per day, or per delivery.
- Confirm your age document and delivery address match the order details.
- Order early enough to accept a signature or show ID at pickup.
Pitfalls That Sink a Cannabis Order
- Counting grams of chocolate as grams of cannabis. A 100 gram bar is not 100 grams of dried product.
- Assuming a low-THC or CBD item sits outside the limit. Products sold by cannabis retailers count.
- Splitting orders across two stores the same day, then carrying both bags home. The public possession limit follows you, not the receipt.
- Planning to cross a border with a legal Canadian purchase. Taking cannabis into another country is illegal, even with a receipt.
- Forgetting that concentrates convert at four to one. Small packages use allowance quickly.
