It's hard to get a decent high-res picture of the CF-18 crash, but coupled with the witness comments about a pop-pop-pop noise and "sparks" from the engine just prior to the departure, this picture shows something interesting.
Take a look at the engine nozzles. You will note that one engine is streamlined while the other nozzle is closed. That would indicate huge differences in thrust between the two engines and could easily account for the yawing departure seen in the crash video.
Whether the differential was caused by a high-AOA compressor stall, a failure of an engine management control, or a last second attempt by the pilot to control the jet remains to be seen.
