Hello - US resident here. Planning Minneapolis to Vancouver on Delta, then a few hours after that flight we plan to use Japan Airlines to Tokyo. I understand baggage will need to be picked up and checked into Japan Airlines. This will be the same route on the way home to Minneapolis.

1. Will we go through customs in Canada before we can check into Japan Airlines flight?
2. When arriving back to Canada from Tokyo do we clear US customs in Canada or will we need to clear both Canadian and US customs on our way home?

Thank you for any advice you can provide!
Pat
