However, the aircraft was not de-iced before takeoff, and the takeoff was commenced with ice contamination on the aircraft.

Almost unbelievable that a Canadian operator would have allowed that to happen. Of all countries, especially after the well documented Air Ontario Flight 1363 crash at Dryden that is used as a training video about what can go wrong in winter ops, I would not have expected this to happen there.
