In answer to your question, you can use a Forever stamp, but it won't be enough on its own. The cost of a US Forever stamp is 49 cents, while the cost of a letter to Canada is $1.20. USPS also sells a Global Forever stamp, as others have noted. You can certainly slap one of those on a letter to Canada.
