The route that surprises me that AC doesn't fly to, maybe because of my lack of knowledge with respect to scheduling, is TPE. I know now that with BR being in *A, that there is even less incentive to fly it, but back as a kid I used to fly CP (and IIRC AC) from YVR to TPE. It surprises me that with such a large asian/Taiwanese community in YVR and YYZ that there isn't a direct flight. Even once a week? Maybe someone can chime in and comment? I'd love to know.
