Within Canada, you can carry medical cannabis with you as long as you have the correct documentation stating you are a recipient of medical cannabis. The Canadian Air Transport Security Authority (CATSA) allows medical patients to fly with cannabis. You can only carry a 30-day limit; which is a maximum of 150 grams of herbs. It is important to note, if you are carrying cannabis oil, you must remain within the limit for liquids (under 100mL). You cannot travel internationally (outside of Canada) with cannabis, with or without a cannabis medical document. It is illegal to carry cannabis out of Canada’s borders – even if you are travelling to a country or state where medical or recreational cannabis is legal.
