That said, what days are you looking at? I picked some random days and there is spotty availability for YYG-YYZ-SFO and YYG-YUL-SFO.
10/10 is the travel date. Remember that "availability" doesn't necessarily translate into showing as available on MP's system.
I must say, I'm always grateful to score an SFO-YYG-SFO saver award any way I can get it, since it's very hard to fly there for under $800-1000 r/t on any date! Far-flung Canadian destinations where AC has little competition are probably some of the most valuable for NA saver awards.
