Russian airline Aeroflot on Sunday violated a ban on aircraft from the country using Canadian airspace, Transport Canada said, on the same day the restriction was imposed in response to Moscow's invasion of Ukraine.

"We are aware that Aeroflot Flight 111 violated the prohibition put in place earlier today on Russian flights using Canadian airspace," Transport Canada said in a tweet late on Sunday.

Transport Canada said it will launch a review into the conduct of Aeroflot and Canada's air-traffic control service provider Nav Canada following the violation.

"We will not hesitate to take appropriate enforcement action and other measures to prevent future violations," the Canadian regulator said.
