That depends. If you are traveling from the U.S. to Canada, your hair dryer, travel iron and cell phone charger will work. Canadian electricity is 110 volts / 60 Hertz, as it is in the United States. Visitors from other continents will probably need to purchase voltage converters and plug adapters.
American cell phones usually work in Canada, depending on your cell phone provider. Before you travel, contact your cell phone service provider to make sure your telephone is configured to make and accept international calls. Otherwise, your cell phone may not work once you cross the border. Expect to pay hefty international roaming charges.
Canada’s ATM machines “talk” with many of the major ATM networks, including Cirrus and Plus. If your bank or credit union participates in one of these networks, you shouldn’t have any trouble using Canadian ATMs. Consult with your bank or credit union before you travel, just to be sure. If you’re traveling in New Brunswick or Québec, the ATM’s instructions will probably be in French, unless you’re in western New Brunswick. Look for “English” or “Anglais” after you insert your ATM card to select English-language instructions.
