A Porter Airlines de Havilland Dash 8-400, registration C-GLQD performing flight PD-539 from Toronto City,ON to Sudbury,ON (Canada) with 78 people on board, was climbing through FL190 out of Toronto when the flight crew noticed smoke on the flight deck, donned their oxygen masks, declared emergency and worked the smoke drill. The captain was unable to communicate with the first officer using the face mask microphone. The captain noticed that the right hand propeller was indicating an overspeed condition, worked the related checklist and shut the right hand engine (PW150) down. The forward outflow valve was opened, the smoke began to dissipate. The crew decided to divert to Toronto's International Airport where the aircraft landed safely on runway 23, the left hand engine was shut down and the APU started. The passengers disembarked rapidly onto the runway and were bussed to the terminal.

The Canadian TSB reported that the smoke was limited to the cockpit, there was no smoke in the cabin. Maintenance determined an internal failure of the right hand engine contaminated the pressure and climate control system for the cockpit.
