For our friends from the US that will be visiting, please carefully read the following information.

Entry into Canada is solely determined by Canadian Border Services Agency (CBSA) officials in accordance with Canadian law, see Visiting Canada this Summer? for details.  Canadian law requires that all persons entering Canada must carry both proof of citizenship and identity.  A valid U.S. passport or NEXUS card satisfies these requirements for U.S. citizens.  If U.S. citizen travelers to Canada do not have a passport or approved alternate document such as a NEXUS card, they must show a government-issued photo ID (e.g. Driver’s License) and proof of U.S. citizenship such as a U.S. birth certificate, naturalization certificate, or expired U.S. passport.  Children under sixteen need only present proof of U.S. citizenship. 

Pets Entering Canada

All pets must be accompanied by their owners when entering Canada. Dogs and cats entering from the US must be accompanied by a certificate signed by a licensed Canadian or US veterinarian certifying that the pet has been vaccinated against rabies during the preceding 36 months. An exception is made for puppies or kittens that are younger than three months old.  See Visiting Canada This Summer? for details.

On June 1, 2009, the U.S. government implemented the full requirements of the land and sea phase of WHTI. The rules require most U.S. citizens entering the United States at sea or land ports of entry to have one of the following:

• U.S. Passport: U.S. citizens may present a valid U.S. passport when traveling via air, land or sea.
• The Passport Card: The passport card is only valid for land and sea travel between the U.S. and Canada, Mexico, the Caribbean region, and Bermuda.
• WHTI-Compliant Travel Documents for U.S. citizen travel via land and sea
