The new entry requirements for traveling to the USA are on this website.
Land and Sea Travel
The implementation of these measures for all land and sea travel to the United States will come into effect at a later time. Canadians can continue to use such documents as their birth certificates and drivers’ licences to cross the Canada-U.S. border by land and sea until the WHTI is fully implemented.
The Government of Canada continues to recommend that Canadians carry a valid Canadian passport when visiting all destinations abroad, including the United States. A passport is the only universally accepted identification document, and it proves that you have a right to return to Canada. Please note that Canadians are not required to have Machine Readable Passports to enter the U.S., even if the passport was issued abroad.
