The drone struck one of the plane's wings, while six passengers and two crew members were aboard.
The aircraft sustained only minor damage and was able to land safely, the Canadian transport minister said.
Earlier this year, Canada announced that it was making it illegal to fly recreational drones near airports.
The law prohibited airborne drones within 5.5km (3.5 miles) of an airport and restricted the height of a drone's flight to 90 metres (300ft).
Those breaking the restrictions could face fines of up to 25,000 Canadian dollars ($20,000, £15,000).
