Keep your passport on your person

Well, that can't always be possible, but these Canadians wish they had their passports on them in this instance.

Their car was seized for a possible connection, though based on the story, the connection is questionable. But Canadians should know police will seize cars and anything on the slightest chance it's involved.

One good trick I tried recently was keeping a copy of the passport in an e-mail account. If my passport is lost, stolen, or confiscated, I can always print out a copy and hope that works. Not the best solution, but better than being stranded like these Canadians.
