Quebec Detention Center (Orsainville Prison), Quebec City, Quebec, Canada
June 7, 2014

Three prisoners escaped in a helicopter piloted by an unknown person. The helicopter landed in the yard of the prison where three prisoners boarded it before it took off westward towards Montreal. The prisoners were at large for over two weeks before law enforcement captured them in a new upscale condominium development in Montreal.

This was the second helicopter escape from a Quebec prison in 15 months. No-fly zones have since been established over Quebec jails.
