Americans who complain about hassles that might occur while crossing into Canada to fish or vacation should know that Canadians face challenges of their own when coming to the United States. That said, the subject here is crossing into Canada. Here are a few ways to make the experience pass as smoothly as possible. Be prepared. Have your passport (or NEXUS card) ready, and those of any passengers. Know what you can bring into Canada. If you’re traveling with your kids, but without their other parent, you’ll likely need a note from the missing parent stating it’s OK for the kids to travel with you.
