Article: All citizens of the United States aged 16 years and older must travel with a passport, passport card, Enhanced Driver’s License or Enhanced ID Card (EDL/ID) to meet requirements for crossing the border to and from Canada.  Bring proof of citizenship (like a birth certificate) in case you are asked for additional documentation. Permanent residents of Canada or the U.S. need to bring their Permanent Resident Cards.  International travelers who are not citizens of the United States or Canada are required to have a passport and possibly a visa when entering Canada. Find out from your home country if a visa will be required. In anticipation of passport processing times, apply for your passport several months before your trip. Passport applications can be completed online and printed, or you can obtain one from a United States post office that has passport acceptance services.  If you need to expedite your passport, you can request and pay for a faster application processing service. You can only complete your passport application online and then print it out for submission. You currently cannot apply for a passport online. Children aged 15 years or younger can cross by presenting proof of citizenship, such as a U.S. birth certificate, without a photo ID. The same goes for children aged 16-18 years old who are traveling with an organized school or other youth group (including religious youth groups).  Valid proofs of citizenship for minors are a U.S. birth certificate (original, photocopy, or certified copy), a U.S. consular report of birth abroad, and a Certificate of U.S. Naturalization. Children (under 18) traveling without both parents should carry a parental consent letter. Ideally, this letter should be notarized. Dogs and cats that are older than three months will need signed and dated rabies vaccination certificates from a veterinarian. These certificates are usually valid for 1-3 years after obtaining them.  Service dogs are exempt from these rules as long as they are accompanied by their owners. The rules about crossing with pets other than cats and dogs vary. Contact CFIA for details prior to your trip.
