Currently, none of the American Express cards issued directly by American Express Canada feature a 0% foreign transaction fee. While the Scotiabank Gold American Express Card and Scotiabank Platinum American Express Card charge no foreign transaction fee, these cards are part of the Scene+ rewards program rather than the American Express Membership Rewards program.

You can use a no foreign transaction fee credit card anywhere that your card type is accepted, whether that’s Visa, Mastercard or American Express. If you’re worried about card acceptance, you could try using a prepaid travel card or get foreign cash before you leave. Keep in mind that ATMs charge currency exchange fees and foreign transaction fees (unless you are withdrawing money from a no-forex fee card).

Foreign transaction fees are charges placed by financial institutions on credit card transactions that involve foreign currency. Foreign transaction fees are around 2.5% typically, and they are charged on top of the currency exchange rate. 

While they were originally established by banks to offset the expense of processing international payments, these concerns have been largely solved by the more modern global banking system of today. Regardless, many credit cards will still charge users a foreign transaction fee, so it's important to know if your chosen card carries this charge before signing up for it (especially if you're a frequent traveller).
