Mere blocks away from Buttonville airport, Canada's tenth busiest airport, a small 4 seat Cessna aircraft crashed into the roof of an office building in Markham.  Firefighters were able to put out the fire caused by the crash, but there is no word yet on how many people were aboard the plane, or if it had taken off, or was landing, or was registered at Buttonville airport.

UPDATE: It has been confirmed by police that the plane did take off from the Buttonville airport and 14 people were evacuated safely from the building, although there is no word yet how many people were on board the plane or if there were any survivors.

UPDATE #2: At least two people died in the plane crash, also the building it hit contained the headquarters for Thinkway Toys.
