American Express is widely accepted at most merchants throughout Canada, according to USA Today. Since American Express offers several different credit card options, travelers should contact American Express directly to find out what specific international restrictions or fees are associated with their card, suggests Fodor's.
American Express offers several benefits specific to traveling, including online booking directly from AmericanExpress.com, travel insurance plans and perks such as airport lounge access, according to Fodor's. These benefits are different for each card that American Express offers.
Before traveling, cardholders should know and understand their card's foreign transaction fee. Most American Express cards charge a 3 percent transaction fee for all international purchases, but this rate varies between cards, says Fodor's. A 3 percent foreign transaction fee is competitive with both Visa and MasterCard as of 2015.
