Flying within Canada
CATSA lists cannabis as permitted in both carry-on and checked baggage. For recreational cannabis, CATSA says passengers are responsible for knowing the law at their destination within Canada. A product legal where you depart may not be legal where you land.
Carry-on liquids and medical cannabis
Liquid and topical cannabis products are subject to carry-on liquids, aerosols and gels limits and must go in the required one-litre clear resealable bag. CATSA lists a separate screening procedure for medical cannabis oil over 100 ml: remove it from the carry-on and present it to the screening officer. Check CATSA's current item page before packing, because security rules can change.
International travel is different
CATSA warns that flying outside Canada with cannabis is illegal. Travel.gc.ca states it is illegal to take cannabis, including CBD-containing products, across the Canadian border unless authorized by Health Canada and the relevant authorities of every country visited or transited through. A medical prescription is not the same as this authorization. Do not assume a legal product or destination policy permits cross-border carriage.
Trip checklist
- Confirm whether the itinerary stays within Canada; ask CATSA or the airline about screening and follow border rules for any international segment.
- Check the destination province or territory's age, possession and use rules.
- Apply carry-on liquid limits to oils and topical products.
- Do not cross an international border with cannabis unless Health Canada and authorities for every country visited or transited have confirmed the applicable authorization.
- Ask CATSA, the airline or border agency when your itinerary or product type is unclear.
