Narrative:

UPDATE TSB #A16O0158: C-GLQL, a de Havilland DHC-8-402 aircraft operated by Porter Airlines, was conducting flight POE204 from Ottawa/MacDonald-Cartier Intl, ON (CYOW) to Toronto/Billy Bishop Toronto City, ON (CYTZ). While passing through 8300 feet approximately 29 nautical miles East on the initial approach to CYTZ, the flight crew noticed an object directly ahead on their flight path. The object appeared to be solid, approximately 5 to 8 feet in diameter and shaped like an upright doughnut or inner tube. There appeared to be no relative movement and the object was rapidly getting closer to the aircraft. The captain overrode the autopilot in order to quickly descend the aircraft under the object. The object passed slightly to the right and above the aircraft. There was no impact. Both cabin crew members were in the process of securing the cabin for arrival and were not seated. They received minor injuries when they were thrown into the cabin structure. The aircraft subsequently landed at CYTZ without further incident. There were no reported passenger injuries or damage to the aircraft.
