I think the Canadian crash is more likely VRS since 350s are much more powerful than Robbos and you would expect HOGE performance to be available at the end of a sortie - and there is no evidence of overpitching unlike the Robbo crash where you can hear the Nr decay.
Perhaps a fine example of the difference between settling with power and VRS. The common factor being a downwind approach and trying to arrest a RoD with power.
