The Cost of Sending a Letter from the US to Canada

As of August 2023, sending a standard letter from the United States to Canada typically costs 1.50 for a First-Class International stamp. This price applies to letters weighing up to one ounce. For additional weight, an extra 0.20 per ounce is added. USPS often updates postage rates, so it's advisable to check their website or visit a local post office for the most current rates.

Using the Global Forever Stamp

For those seeking a more convenient and cost-effective option, the Global Forever stamp offers a solution. This stamp, currently priced at 1.40, allows you to send one-ounce standard letters or postcards around the world without the concern of future postage rate increases. Even if USPS raises the price, the Global Forever stamp will continue to be valid. Alternatively, you can use three Domestic FOREVER Stamps (at 0.60 each) or two Domestic FOREVER Stamps plus an additional 0.20 in other stamps to achieve the same.

The Global Forever stamp can be purchased online at the USPS website or from your local post office.

Varying Costs Depending on Origin

While the cost of sending a one-ounce standard letter to Canada is currently 1.40, this might vary slightly based on postage rates or additional service options. The cost remains consistent regardless of where in Canada you are located. The calculation is quite straightforward: stamps of any denomination totaling 1.40 in postage can be used, or a Global Forever stamp priced at 1.40 can be utilized.

Other Considerations for Mailing Letters and Packages

The postage cost for a package depends primarily on its size and weight. Local post offices in the area where you live provide the most accurate information. For instance, in Canada, Canada Post offers a flat rate for sending gifts weighing up to 5 kg, provided the item fits in a standard flat rate box. This service is available anywhere in Canada.

For different shipping methods and rates, it's best to visit the post office in person. If you live in the US, the following rates apply for First Class envelopes weighing up to one ounce: 1.15 for delivery in 6–10 days, and 1.20 starting on January 26, 2020. Global Forever stamps, currently priced at 1.15, provide another convenient option.

For additional convenience, stock up on Global Forever stamps now, as the price may increase in the future. USPS often adjusts rates, so it's practical to have access to stamps that remain valid regardless of future changes.
