Research AC Rouge and you will never fly them. On a B767, Rouge fits in 10 more rows of seats than a standard AC B767. Leg room (even for a short guy like me) is non-existent!
Air Canada's service is so bad that the Flight Attendants even joke about it with customers. I once had an Air Canada (Scare Canada) Flight Attendant tell me "Hey if you want good service, fly WestJet. Here, you get what you get." Yes, they said it "tongue in cheek", but there was more than a grain of truth in their statement.
BTW, I have a trip coming up soon to beautiful, sunny "Lost Wages" NV. I am flying Air Canada there (YYZ-LAX-LAS) on a B787 for the YYZ-LAX leg and Air Canada Rouge on a B767 non-stop on the way home.
