Make sure you're up-to-date with recent changes in border crossing requirements for Canada.
Entering Canada
When visiting the Yukon, you can enter Canada by land or air. If driving into the Yukon from Alaska, you will cross the U.S.-Canada border at one of these checkpoints: Fraser Customs (from Skagway), Little Gold Creek Customs (Top of the World Highway), Beaver Creek Customs (Alaska Highway) and Pleasant Camp Customs (from Haines). If flying directly to the Yukon from outside Canada, you will go through customs in Whitehorse or Dawson City. If you are a United States citizen, please refer to the United States Embassy for specific information.
Entering Canada for citizens of other countries than the United States
If you’re visiting Canada from a country other than the United States, you will need proof of citizenship and residency. Proper identification includes passports, birth certificates, citizenship cards and certificates of Indian Status. To avoid problems and delays in clearing customs, make sure you have proper identification for yourself and any children traveling with you. Visitors from some countries may need a visa – check with Citizenship and Immigration Canada.
Children entering Canada
Minors travelling alone must have proof of citizenship and a letter from both parents detailing the length of stay, providing the parents’ telephone number and authorizing the person waiting for them to take care of them while they are in Canada.
If you are travelling with minors, you must carry proper identification for each child such as a birth certificate, passport, citizenship card, permanent resident card or Certificate of Indian Status.
If you are divorced or separated, you should carry with you copies of the legal custody agreements for your children. If you are travelling with minors and you are not their parent/guardian, you should have written permission from the parent/guardian authorizing the trip. The letter should include addresses and telephone numbers of where the parents or guardian can be reached and identify a person who can confirm that the children are not being abducted or taken against their will.
If you are travelling with a group of vehicles, make sure you arrive at the border in the same vehicle as your children, to avoid any confusion.

Pets
If you are bringing a pet dog or cat into Canada, a valid rabies vaccination certificate signed by a licensed veterinarian is required. For more information on pets other than cats or dogs please review the regulations of the Canadian Food Inspection Agency.
