Two commercial airplanes collided on a tarmac at Toronto Pearson International Airport on Friday night, sparking a small fire and prompting the evacuation of dozens of passengers, CNN reported.

A Sunwing Airlines aircraft backed out while being towed, hitting a WestJet plane that had arrived from Cancun and was waiting to proceed to a gate, officials said.

There were 168 passengers and six crew members aboard the arriving airplane, according to Lauren Stewart, a WestJet spokeswoman. There were no passengers or crew on the Sunwing aircraft. It was being towed by a “ground handling service provider,” the airline tweeted.
