Prime Minister Justin Trudeau announced Friday that Air Canada, WestJet, Sunwing and Air Transat had agreed to the measure in an effort to slow the spread of COVID-19.
The restriction will last until April 30, and Trudeau says the airlines will help arrange the return of customers currently on a trip.
It's one of a suite of new government measures aimed at preventing Canadians from travelling abroad in the doldrums of February and throughout spring break.
For instance, starting first thing Thursday, all international passenger flights must land at only four airports -- in Vancouver, Toronto, Calgary, and Montreal.
And in the coming weeks, all air travellers arriving in Canada will have to stay at a government-approved hotel for three nights and take a COVID-19 test -- all at their own cost.
