How different screening will be for patrons at airport security checkpoints is still being ironed out. The Canadian Air Transport Safety Authority which oversees our country’s airport screeners says it expects “to finalize our procedures in the coming days.”

This new protocol at airports, however, does come with a word of warning for passengers.

It will still be against the law to pack bags with pot when travelling internationally even into areas or U.S. states where marijuana is already legal.

“As long as the flight is domestic, people are allowed to bring up to a certain quantity for their personal use,” Federal Transport Minister Marc Garneau said.

“However, I would remind people if they’re going to a country like the United States – the rules of that country are the rules that apply.”

While pot is legal in several U.S. states, it’s not on a federal level and you could face serious criminal penalties. It is also illegal to transport cannabis used for medical purposes across international borders.

When flying high, people won’t be able to smoke pot onboard any aircraft in accordance with the Canadian Aviation Regulations. It will also be forbidden to light one up while waiting to board a plane at the Saskatoon Airport.

“You’re not able to smoke cannabis here at the airport similar to drinking in public,” Saskatoon Airport Authority CEO Stephen Maybury said.

Transport Canada said it is working to post signage advising travellers of the new rules and that they’ll be installed at airports, ferry and cruise terminals, and railway stations at exit points from Canada. With respect to land crossings, it is working with provinces and territories to install road signs near the border.
