According to Transport Canada, passengers can carry up to 30 grams of cannabis on flights within the country once cannabis becomes legal on October 17.

Global News reports that Canada’s Minister of Transport - and former astronaut - Marc Garneau said, "as long as the flight is domestic, people are allowed to bring up to a certain quantity for their personal use.”

However, passengers are cautioned not to travel with cannabis if they are on international flights or crossing the border to the United States. Even though cannabis is legal in some American states, it remains federally illegal, and people bringing cannabis to the states could be subject to arrest and criminal penalties.

How will cannabis affect wait times and screening at Canadian airports? That’s still up in the air (pun intended). However, the Canadian Air Transport Safety Authority says it expects "to finalize our procedures in the coming days.".
