There was only 1 incident in my whole flying career which is about 15 years. Almost all my travel is with Canadian.
It was a flight about 5 or 6 years ago from YYZ - YVR on a DC-10. The aircraft was rolling on the runway and then at near the point of takeoff which they call V1, they decided to abort takeoff, a lot of people on board thought they were not going to have enough runway to stop, however they just did. Turn out that they lost complete power on one of the engine..good thing that didn't happen after take off. Towed back to the gate for 5 hours before taking off again on the SAME aircraft. Beside from that, all of my travel on CP has been "scare free".
