Drivers of American cars will need to carry a Canadian Non-Resident Insurance Certificate in addition to their standard insurance card and must be prepared to present both documents for inspection. The Certificate comes in the form of a yellow paper card which can only be issued by foreign insurers who are authorized to do business in Canada.
Thousands of people cross over into Canada every day and I will guarantee you thousands of people have no idea what this is and have NEVER or will NEVER be asked for it.
For me without even asking about it my insurance is valid in both the Canada and the US. Never heard of anyone from the US I know travelling who's insurance was not good on both sides of the border.
Something I'd not worry about.
