The short answer

Yes, adults of legal age can fly with legal cannabis on flights within Canada. Follow the federal public possession limit of up to 30 g of dried cannabis, or the legal equivalent in other formats. Keep packages sealed when possible, and always follow airline rules and airport screening guidance. Never take cannabis on international flights, even to countries that have legal markets. Once you cross a border, different laws apply.

Who can carry and how much

On domestic trips, adults of legal age may carry up to 30 g dried cannabis equivalent in public. This rule covers both the airport and the airplane. You can split the total across several products: flower, pre-rolls, vapes, oils, capsules, topicals, and edibles. The key is to add up the dried cannabis equivalence numbers printed on each legal package. You do not need to do conversions yourself because the label already shows how much that package counts toward the 30 g total.

Carry-on or checked bag?

Screening rules allow cannabis in carry-on and checked bags on flights within Canada. Many travellers choose carry-on so items stay with them and do not get lost, but you can choose either if the airline permits it. Pack products so labels are visible. Keep liquids (like oils) within the normal liquid limits for carry-on, or place them in checked bags to avoid delays at the checkpoint.

Packing tips for a smooth screening

• Keep products sealed and labeled. Use the original child-resistant containers. Do not transfer products into unlabeled jars or baggies.
• Group items in a small pouch. This makes it easy to remove them if screening staff ask to see them.
• Follow liquid rules. If you bring oil, place it in a clear 1-litre resealable bag with other liquids if it is in carry-on.
• Keep batteries safe. 510 batteries and disposables with lithium cells should travel in carry-on rather than checked, with the device switched off.
• Bring your ID. You must still meet normal ID rules for air travel. Some airports also post reminders that cannabis is for adults of legal age only.

How to use the “dried cannabis equivalent” line

Every legal package lists a number such as “dried cannabis equivalence: 2 g.” Add these numbers across all items you bring. Stop when the sum reaches 30 g. Here are examples:

• A small edible package might list “dried cannabis equivalence: 2 g.”
• A vape cart may show a different number based on size and potency.
• Flower lists its own simple gram weight, which counts directly toward the 30 g total.

If you are unsure, carry fewer items and keep them sealed. You can always buy more at your destination.

Medical cannabis travelers

People authorized for medical cannabis have different possession rules tied to their authorization. If that is you, carry your documents and follow the medical framework that applies to your amount, packaging, and plant material. If you do not have an authorization, the non-medical limit of 30 g dried equivalent applies to you.

What you should not do

• Do not cross international borders with cannabis. This includes flights to and from the United States. Leave cannabis at home for international trips.
• Do not open or use cannabis in the airport or on the plane. Rules treat cannabis like smoking. Keep products sealed until you are on private property where use is allowed.
• Do not pack unlabeled items. Loose nugs or unmarked edibles will slow you down and can cause issues at screening.
• Do not put loose batteries in checked bags. Keep vape batteries in carry-on with the device off.

How to plan your trip

1. Check your airline. Look for a short page on carry-on limits and lithium battery rules.
2. Review your amounts. Add up dried cannabis equivalence across all items and keep the total at or below 30 g.
3. Pack smart. Keep labels visible, group items together, and follow liquid rules.
4. Leave it sealed. Do not open packages in the airport or on the plane.
5. Know the rules at your destination. Provincial rules can differ on where you can use cannabis once you land.

Frequently asked questions

Can I bring edibles in my carry-on?

Yes, on flights within Canada, as long as your total public possession stays at or below 30 g dried equivalent. Keep edibles sealed and in the original package.

Can I bring a vape?

Yes. Keep devices with lithium batteries in carry-on, powered off. Follow airline rules and do not use the device on the plane.

Can I fly with cannabis seeds?

Seeds sold in legal stores are allowed on domestic flights, but keep them sealed and labeled.

What if I am connecting through a U.S. airport?

You cannot carry cannabis across an international border. If your routing touches the U.S., do not bring cannabis.

Is the 30 g rule the same everywhere in Canada?

The federal public possession limit is 30 g dried equivalent. Provinces can have different rules about where you can use cannabis after you land. Check local guidance for your destination.

Bottom line

For flights within Canada, adults can travel with legal cannabis if they keep the total at or below 30 g dried equivalent and pack items sealed and labeled. Keep vapes powered off in carry-on, follow liquid rules for oils, and never cross international borders with cannabis.
