I know this is an old post, do you know if a rental car is considered a commerical carrier that would require you to show your PR Card. I a newly landed immigrant to Canada and I have to travel back to the US for business. But I need to come back to Canada within the week. I was first thinking I could fly to Buffalo and take the bus but then I think it is also considered a commerical carrier. So besides my family coming to pick me up can I rent a rental car so I don't have to apply for the travel document with the Canada Visa's office in the state.
