Flying out of Pearson with cannabis: what's allowed on domestic flights, and why it can't go international

Last checked: October 19, 2026
Green Air Cannabis sits at 7060 Airport Rd in Malton, on the Pearson corridor. Because we're this close to the airport, one of the questions we hear most at the counter is some version of "Can I take this on my flight?" The honest answer is: it depends entirely on where the plane is going. Here's how the rules split, in plain terms, with links to the federal pages that set them.

Think of this as a starting point for adults 19+ rather than legal advice. Travel rules do change, so open the linked sources before you pack.

The short version

Domestic flights: the checklist

If you're flying from Pearson to another Canadian city, the Canadian Air Transport Security Authority (CATSA) says cannabis is allowed in both carry-on and checked bags. Before you head down Airport Road, run through this list:

1. Stay under 30 grams. Federal law caps what an adult can carry in public at 30 g of dried cannabis, or the same amount in another form. That limit applies in the airport and on the plane, just like on the street.
2. Liquids follow the liquids rule. CATSA treats cannabis oils and topicals like any other liquid, aerosol or gel in your carry-on: containers of 100 mL or less, all together in one clear, resealable 1-litre bag.
3. Keep it in its original packaging. The label shows exactly what the product is.
4. Know the rules where you land. Each province and territory sets its own rules, including the legal age, where you can consume and where you can buy. British Columbia's government travel page makes the same point. Being 19 and legal in Ontario doesn't settle the question for another province, so check the official site for wherever you're landing.
5. Think about re-routing. British Columbia's government travel page makes a point worth repeating: if a domestic flight gets diverted to another country, Canadian law no longer protects you there.

International flights: leave it at home

This one is simple. The Government of Canada's travel site is clear that it's illegal to take cannabis across the border, whether you're leaving or coming back, whatever the amount, and even if you're travelling to or from a place where it's legal. That covers edibles, extracts, topicals and anything containing CBD.

So if your trip out of Pearson ends up in Florida, Jamaica or anywhere else outside Canada, the right amount of cannabis in your bag is zero. The travel.gc.ca rule also covers countries you only pass through, so a connecting flight through a U.S. airport means taking cannabis across the border, even if your trip ends in another Canadian city.

Coming back into Canada

If you're returning to Pearson and you have cannabis with you in any form, you're required to declare it to border officers (the CBSA). The CBSA warns that not declaring it could lead to arrest and prosecution. The safest plan is not to bring any back at all.

At the airport itself

Toronto Pearson's own smoking policy says cannabis smoking or vaping is not allowed anywhere on airport grounds. Inside the terminal buildings is smoke-free and vape-free at all times. Pearson has 10 designated outdoor smoking areas, on all levels of Terminals 1 and 3, for people who vape, and they don't change the cannabis rule: no cannabis anywhere on airport grounds.

Getting to the airport has its own rule: in Ontario, you can't consume cannabis in any form (smoking, vaping or eating) in a vehicle that is being driven or will be driven. That applies to passengers too, including in a rideshare or taxi to the terminal (Ontario's "Cannabis laws" page on ontario.ca covers this).

Getting between Malton and the terminals

A few practical notes for people who live or work near us:

• Airport Road is the main north–south road through Malton, and our counter at 7060 is right on it.
• MiWay buses run along Airport Road through Malton. Routes change, so check miway.ca for the current trip before you leave.
• For parking and directions to the store itself, see our visit page.
• For what's on the shelves at our weed dispensary in Mississauga, check the page before you come by. If you'd rather not make the trip, our weed delivery in Malton page explains how ordering works.

None of this changes the rules above.

Quick answers

Can I use cannabis while I wait for my flight?
No. Pearson doesn't allow cannabis smoking or vaping anywhere on airport grounds, including the outdoor smoking areas.

Can I pack edibles in my checked bag for a flight to Vancouver?
Yes, as long as your total stays within the 30 g equivalent and you follow British Columbia's rules when you land.

I'm flying to the U.S. for a day. Can I bring a small amount?
No. Any amount is illegal to take across the border.

Does a medical document let me fly internationally with cannabis?
Not on its own. The travel.gc.ca page explains that travelling internationally with cannabis for medical purposes needs a specific exemption from Health Canada, which is issued only rarely.
