The incident in Quebec was captured on film by witness Mathieu Leclerc and shows the aeroplane coming down lower and lower over the roadway, until eventually it becomes clear this is not just a low pass or an accident, but a well-controlled landing.
It happened on Highway 40 in Quebec City on Thursday morning.
The plane is travelling in the same direction as the cars, and makes a smooth landing surrounded by vehicles.
Though the traffic appears to slow down, none of the drivers appear to stop completely as the plane touches down, and as soon as the aircraft comes to a halt, the cars caught directly behind it then move off around it and continue their journeys.
