How many entries does a Canadian transit visa give me, and what if I connect both ways?

A transit visa is not always single-use. It can be valid for one or two entries depending on how your trip is structured.

If you connect through Canada only on your outbound journey, a single entry is enough. If your return flight also routes through a Canadian airport, you will need a two-entry transit visa so you are covered in both directions. Make sure your application reflects your full itinerary so the visa matches how you will actually travel.
