Flying With Cannabis From Toronto Pearson: What Is Allowed

Domestic flights allow legal cannabis within the 30 g limit; international flights, including to the US, never do. CATSA and border rules for flying from Toronto.

Yes, you can fly with legal cannabis within Canada: CATSA (the Canadian Air Transport Security Authority) allows cannabis in both carry-on and checked bags on domestic flights, within the 30-gram public possession limit. No, you can't take it on any flight leaving Canada, including flights to the United States, even if cannabis is legal where you are going.

Here is what to know before you pack, as of 2026.

Domestic flights from Toronto Pearson

CATSA's cannabis page lists cannabis as allowed in carry-on and checked baggage on flights within Canada. It adds one important line: passengers are responsible for knowing the laws and regulations in effect at their destination within Canada.

That means three things for a flight from Pearson to Vancouver, Calgary, Halifax or anywhere else in the country:

1. The 30 g limit still applies. Under the federal Cannabis Act, adults can possess up to 30 grams of dried cannabis, or the equivalent, in public, and that limit travels with you. Our guide to cannabis possession limits in Ontario shows how vapes, edibles and beverages count toward that 30 g.
2. The legal age changes with the province. Health Canada notes the legal age is 18, 19 or older depending on the province or territory. Check your destination's age before you fly.
3. Your destination's own rules apply to where you can consume and how much you can have, so look them up on that province's official site.

What 30 grams looks like in a carry-on

The federal Cannabis Act's Schedule 3 converts each product type to a dried cannabis equivalent. Using those figures:

• 30 g of dried flower or pre-rolls is the full limit on its own.
• One 1 g vape cartridge counts as 4 g of dried cannabis, so seven cartridges come to 28 g.
• A 355 ml cannabis beverage counts as roughly 0.6 g, but as a liquid it still has to follow the carry-on liquids rules.

Mixing products adds up quickly, so total everything before you leave home.

Liquids, oils and beverages

CATSA treats recreational cannabis in liquid or topical form, such as oils and drops, under the same rules as other liquids, aerosols and gels. In your carry-on, they go in your 1-litre clear, resealable bag with your other liquids. Cannabis beverages are liquids too, so plan accordingly or pack them in checked baggage.

Vapes and cartridges

CATSA's page on electronic cigarettes and accessories lists vaping devices as allowed in carry-on, with refill liquid limited to 100 ml or less. For checked baggage, it says to check with your airline. Ask your airline about vape devices and batteries before you pack.

Medical cannabis

Medical cannabis has its own rules. CATSA says medical cannabis oil over 100 ml is allowed in carry-on but must be taken out and shown to the screening officer, and the amount you carry must follow federal medical cannabis rules. Talk to your healthcare provider and check CATSA's page before travelling with medical cannabis.

International flights: leave it at home

This is where people get into trouble. The Government of Canada's travel advice on drugs is direct:

• It is illegal to take cannabis, including products containing cannabis, across the Canadian border, in or out.
• This applies even if you are travelling to or from a place where cannabis is legal or decriminalized.
• It applies no matter how much cannabis you have.
• It covers all products containing CBD.
• Travelling to other countries, including the United States, with any amount of cannabis can lead to criminal charges and being denied entry to other countries in the future.
• If you arrive in Canada with cannabis in any form, you must declare it to the Canada Border Services Agency.

The federal Cannabis Act itself states that, unless authorized under the Act, importing or exporting cannabis is prohibited. If your trip leaves Canada at any point, don't bring cannabis.

Practical tips before a domestic flight

• Keep products in their original, labelled retail packaging. Labels show the product type and THC and CBD amounts, which makes it easy to show what you are carrying and to stay inside the 30 g limit.
• Keep your receipt with the products if you bought them recently.
• Don't consume at the airport. Ontario bans smoking and vaping cannabis in enclosed public places, and that includes terminal buildings.
• Don't consume before driving to or from the airport. See our cannabis and driving guide.
• Edibles: Ontario limits each package to 10 mg of THC. If you are new to edibles, start low and go slow, and wait before having more.
