Crossing the Border: Five Things U.S. Travelers to Canada Should Know

While Americans used to be able to drive across the Canadian border without even a second thought, there have been many changes over the last decade, and crossing into Canada now requires a lot more than a wave and smile to the border patrol agent.

Having lived in northern Washington state for six years in the nineties, I crossed the border numerous times with no problems whatsoever. I made several trips with my young daughters to the Vancouver Aquarium in British Columbia, and the only question I was asked was how long I planned on being there.

Unfortunately, things have changed, and there are many regulations that you should be aware of before you make that crossing.

Traveling with children

One of the major changes in the border crossing has to do with children. Parental abductions have become a big concern in recent years, and Canada is one of the countries that has taken this very seriously. Divorced parents should be aware that a notarized letter from the absent parent giving the parent permission to go into Canada with their child, or children, is required.

Even if you are not divorced, if both parents are not traveling, you must bring the permission letter from the absent parent. Include detailed contact information for the other parent, and be sure that they will be available about the time of your crossing if the border guard needs to contact them. It is important that the parent is also aware of your itinerary, in case questions are asked as to what your plans are in Canada. If your stories don't match, you won't be allowed into the country.

If you are traveling with children who are not your own, it is also recommended that you bring a medical authorization letter from the child's parents in case of medical emergency.

The best identification to bring is a passport, but for children, a birth certificate is acceptable.

Adult identification

Adults must have either a passport of an enhanced driver's license or id card.

Prior criminal offenses

Another big change at the border, is that if you have been convicted of any type of crime, you could be turned away at the border. One of the more common situations, is a person who has been convicted of a DUI in the United States, is considered a felon in Canada, and will not be allowed to enter. If you there is any question as to whether you will be allowed to travel into Canada, be sure and check the latest regulations before your attempt.

Prohibited items

There are some items that you might not be aware are not allowed into Canada. Always checked the most recent updated list before leaving for Canada. Some of the items that are prohibited include radar detectors, live minnows or worms, firewood, potatoes and dog food.

Bring pets into Canada

You can bring your dog or cat as long as they have a valid rabies vaccination certificate signed and dated by a veterinarian within the last 36 months. Be sure that it also includes a description of your pet, so he can be identified.
