It depends on the airline. AC cannot offer US-CA-US itins (as it doesn't have seventh freedom rights in the US), but can offer CA-US-CA. Likewise, UA cannot offer CA-US-CA tix but can offer US-CA-US.
It doesn't really matter where you connect, UA cannot fly you from a Canadian city to another Canadian city (as your start and end points). AC can't do routes such as SEA-YVR-NYC either. Where you connect is irrelevant.
