Calculate your postage rate using the international postage price calculator. For a first-class letter to Canada, the first ounce of postage costs 85 cents, a two-ounce letter costs $1.17 and a three-ounce letter costs $1.49, as of the time of publication.
First Class packages to Canada are limited to no more than 4 pounds, for example. You can ship packages up to 66 pounds to Canada via Express or Priority mail. With these two methods, a basic 20-lb. package costs $116.95 and $71.70, respectively, at the time of publication. You can cut these costs almost in half by using U.S. Postal Service flat rate boxes.
