International postage rates apply whenever you send letters or packages from the United States to Canada. Being a neighboring country, and a friendly and stable one at that, Canadian postage rates aren’t especially high, and the service is fast and reliable. As of 2014, an ordinary letter sent via First-Class Mail International costs between $1 and $3 to send, while large envelopes under 64 ounces cost between $2 and $19. Priority Mail International tends to be less expensive, but it also takes longer, while Global Express Guaranteed is the fastest and most expensive service.
USPS Rate Calculator and Rate Schedules
The U.S. Postal Service offers an online postage price calculator (see Resources). Select “Canada” from the drop-down menu and enter the type of envelope or box you’re sending. Then USPS will show you which of its shipping services are available and how much each of those services will cost. As an alternative, you can calculate your rate using the most current USPS rate schedules.
