And yes there was a fair bit of discussion that AC struck something with SQ to have access to award seats (though I don't imagine that came for free).
I read his post as the air frame doing asia-YVR, YVR-YYZ/YUL, then YYZ/YUL-Europe all in sequence. I'll add my interpretation that the aircraft would then do the reverse on the return, Europe-YYZ/YUL, YYZ/YUL-YVR, YVR-Asia.
However I am not sure even with an early morning arrival the aircraft can be turned around at YVR fly to YYZ/YUL, then turn around in time to fly the early evening/evening European departures.
