Flying WestJet should be seen as a viable third option tbh. If for no other reason than to say to AC.. I fly 50 segments a year with you, and I don't have enough aeroplan points for 1 reward flight. I'll take my business elsewhere.

Not saying you should do that, but it's something to consider. Possibly even going with AAvantage program if you can fly 4 segments a year with them. 100% miles on all WS flights and access to the Oneworld alliance for rewards.
