The ones I recently noticed are airports in Thailand. Since Thai Smile is being rolled back into Thai Airways, TG serves a bunch of domestic destinations, most of which AC's web site doesn't allow. If you want to fly to CEI, UBP, UTH, etc, on TG, you can book on United MileagePlus, but you can't even enter those codes into the search on Air Canada's site.
