Ontario's 30 g public limit, converted for vapes, edibles, beverages, hash and seeds, with worked examples and a mixed-basket calculation.
In Ontario, adults 19 and older can carry up to 30 grams of dried cannabis, or the equivalent in other forms, in public. The federal Cannabis Act sets those equivalents in Schedule 3: for example, 7.5 g of concentrates, 450 g of edibles or about 17.1 litres of cannabis beverages each count as the full 30 g.
Below is the full conversion table, worked examples with real product sizes, and the rules on buying and sharing, as of 2026.
The rule in one line
Ontario's cannabis laws page says you can have a maximum of 30 grams (about one ounce) of dried cannabis, or equivalent, in public at any time. That comes from section 8 of the federal Cannabis Act, which bars adults from possessing more than the equivalent of 30 g of dried cannabis in a public place.
The same 30 g figure is the limit per transaction when you buy. The AGCO says customers can't purchase more than 30 grams of dried cannabis, or the equivalent, at one time, and the Ontario Cannabis Store applies the same limit to each online order.
The 30 g equivalents table
Schedule 3 of the Cannabis Act lists how much of each class of cannabis is deemed equal to 1 g of dried cannabis. Multiply by 30 and you get the public limit for each type on its own:
| Class of cannabis | Equals 1 g dried | Equals the 30 g limit |
|---|---|---|
| Dried cannabis (flower, pre-rolls, blunts) | 1 g | 30 g |
| Fresh cannabis | 5 g | 150 g |
| Solids containing cannabis (edibles such as gummies and chocolates) | 15 g | 450 g |
| Non-solids containing cannabis, other than beverages (for example topicals) | 70 g | 2,100 g |
| Cannabis concentrates (vape oil, hash, rosin, live resin, diamonds) | 0.25 g | 7.5 g |
| Cannabis beverages | 570 g | 17,100 g, about 17.1 L |
| Cannabis plant seeds | 1 seed | 30 seeds |
Two details from Health Canada's possession limit calculator help here:
- Beverages: 1 millilitre of cannabis beverage counts as 1 gram.
- The 3% line: the calculator treats solids and non-solids as products at 3% THC or less. Anything over 3% THC, solid or liquid, counts as a concentrate. That is why vape oil and hash use the strictest ratio.
The calculator also notes that dried cannabis equivalency amounts appear on the labels of other retail cannabis products, so the label is a quick shortcut.
Worked examples
The math below is our own, using the Schedule 3 figures above.
Vape cartridges. A 1 g cartridge is a concentrate, so it counts as 4 g of dried cannabis. Seven 1 g cartridges come to 28 g. An eighth would take you over the limit.
Hash and rosin. 1 g of hash or rosin also counts as 4 g. A 2 g jar counts as 8 g.
Edibles. Edibles are measured by the weight of the product, not the THC. A 15 g package of gummies counts as 1 g of dried cannabis. You would need 450 g of edibles to reach 30 g.
Beverages. A 355 ml can counts as roughly 0.6 g of dried cannabis, so it takes about 48 cans to reach the limit.
A mixed basket.
| Item | Dried cannabis equivalent |
|---|---|
| 14 g of dried flower | 14 g |
| Two 1 g vape cartridges | 8 g |
| Four 355 ml beverages | about 2.5 g |
| One 15 g package of gummies | 1 g |
| Total | about 25.5 g |
That basket is under the 30 g limit for one purchase and for carrying in public. Swap the gummies for a 2 g jar of rosin and the total rises to about 32.5 g, which is over.
Buying, sharing and the under-19 rule
- Buying: Every legal store and OCS.ca caps each transaction at 30 g dried or equivalent. A legal store can't sell you more than that in a single purchase, online or at the counter.
- Sharing: Under the federal Cannabis Act, an adult may not distribute more than the equivalent of 30 g of dried cannabis, and may not distribute cannabis to anyone under 18. In Ontario you must be 19 or older to possess cannabis at all, so never give cannabis to anyone under 19.
- Edibles per package: Ontario limits edibles to 10 mg of THC per package, and the OCS notes extracts and topicals are capped at 1,000 mg of THC per package.
Growing at home
Ontario allows up to four plants per residence, for adults 19 and older, using seeds or plants from the OCS or an authorized store. Seeds count toward the public limit one for one, so carrying 30 seeds reaches the full 30 g on its own.
Medical cannabis
People authorized to use cannabis for medical purposes follow separate federal rules. Talk to your healthcare provider and check Health Canada for the current limits.
Why the limit matters when you travel
The 30 g limit applies in public anywhere in Canada, including on domestic flights. Crossing the border with any amount is illegal. Read flying with cannabis from Toronto before you pack, and cannabis and driving in Ontario for the rules on carrying it in a car.
Responsible use, in short
- Start low and go slow, especially with edibles and concentrates.
- Keep products sealed, labelled and locked away from children and pets.
- Never drive after consuming.

Frequently asked questions
What is the cannabis possession limit in Ontario?
Adults 19 and older can have up to 30 grams of dried cannabis, or the equivalent in other forms, in public at any time. The same 30 g limit applies to each purchase from a legal store or the Ontario Cannabis Store.
How many vape carts equal 30 grams?
Under Schedule 3 of the Cannabis Act, 0.25 g of concentrate equals 1 g of dried cannabis, so a 1 g cartridge counts as 4 g. Seven 1 g cartridges come to 28 g, and an eighth would put you over the 30 g limit.
How do edibles count toward the 30 g limit?
Edibles count by the weight of the product, not the THC. 15 g of a solid edible equals 1 g of dried cannabis, so you would need 450 g of edibles to reach the limit. Each edible package in Ontario can contain up to 10 mg of THC.
How many cannabis drinks can you carry in Ontario?
570 g of cannabis beverage equals 1 g of dried cannabis, and Health Canada counts 1 ml as 1 g. That works out to about 17.1 litres for the full 30 g, or about 48 cans of 355 ml.
