One of the most common questions from cannabis consumers — especially those who are newer to the legal market — is how much weed can you carry in Canada legally. The Cannabis Act sets a clear federal limit, but the details around equivalencies, provincial variations, and what counts as "public" possession trip people up. Let's break it all down.
The 30-Gram Federal Limit: What It Actually Means
Under the Cannabis Act, any adult of legal age can possess up to 30 grams of dried cannabis (or its equivalent) in a public place. This is a federal rule that applies across every province and territory. It's important to note that this limit only governs what you carry in public — there is no federal limit on how much legally purchased cannabis you can store in your private home.
The 30-gram cap is measured in dried-flower equivalent. Since cannabis comes in many forms, Health Canada established conversion ratios so everything can be expressed as a single number:
| Product Type | Equivalent to 1 g Dried Flower |
|---|---|
| Fresh cannabis | 5 g |
| Edibles (solid or liquid) | 15 g |
| Concentrates (shatter, wax, hash) | 0.25 g |
| Cannabis liquid (beverages, tinctures) | 70 g (or 70 ml) |
| Seeds | 1 seed |
| Plants (non-budding) | 1 plant |
So if you're carrying 7.5 grams of concentrates, that's already your full 30-gram equivalent. Carrying a mix? Add up each product's equivalent weight and make sure the total stays at or below 30 grams. For a deeper dive into how concentrates factor in, take a look at our concentrates guide.
Provincial Variations: Age and Other Rules
While the 30-gram public possession limit is federal, provinces set their own legal age. In Ontario, Alberta, and most other provinces, you must be 19 to purchase and possess. Quebec is also 21, which is worth knowing if you're travelling between provinces.
Some provinces also have additional rules. For example, certain provinces restrict where you can consume (parks, patios, vehicles), and a few have placed limits on the THC content of edibles sold in retail beyond the federal 10 mg cap per package. Always check the local rules when you're travelling within Canada.
Can You Carry Cannabis Across Provincial Borders?
Yes. Since the Cannabis Act is federal, you can transport cannabis between provinces as long as you stay within the 30-gram public possession limit. The product must be legally purchased, and you should keep it in its original packaging when possible. This makes it easy to prove it came from a licensed source if you're ever asked.
Flying Within Canada With Cannabis
You can fly domestically with up to 30 grams of dried cannabis or equivalent. It should be in your carry-on or checked luggage, and it must comply with airline and airport security rules. However, you absolutely cannot bring cannabis across international borders — even to countries where it's legal. Attempting to cross the US-Canada border with cannabis can result in serious criminal charges and a travel ban.
What Happens If You Exceed the Limit?
Carrying more than 30 grams of dried equivalent in public is a criminal offence under the Cannabis Act. Penalties can include fines and up to five years in prison for adults. In practice, first-time offences for small overages are unlikely to result in maximum sentencing, but it's still a criminal record you don't want.
