The Transportation Safety Board has dispatched a team to Toronto after a Porter Airlines aircraft nearly collided with what’s believed to be a drone.
The TSB says the plane was about 50 km east of Toronto, en route from Ottawa to Billy Bishop Airport around 7:30 a.m. EST, when an object of some kind was spotted dangerously close to its flight path.
Porter Airlines says crews took evasive action and were able to avoid a collision, but two flight attendants were taken to hospital with minor injuries.
The airline says the pilots initially believed the object to be a balloon, but they now think a drone may have been to blame.
Federal regulations ban the use of UAVs within 9 kilometers of an airport, and must not be flown higher than 90 meters. Fines for violators go as high as $25,000.
But as drones get cheaper and more popular, they’re becoming a growing concern for aviators.
WATCH: This drone video, while beautiful, kicked off a Transport Canada investigation when it emerged it was shot next to the King George Airpark
UAVs have been spotted near Vancouver’s YVR on several occasions, prompting the airport to join with Transport Canada to launch a drone safety campaign.
A viral video of people ice skating on Surrey’s Serpentine Fenn also sparked at Transport Canada investigation when it emerged the pilot was flying next door to the King George Airpark.
And B.C. wildfire crews have been frustrated on several occasions when drones turned up in their airspace, forcing teams to ground fire fighting helicopters.
