One. From USPS web site: "Forever Stamps can be used to mail a one-ounce letter regardless of when the stamps are purchased or used and no matter how prices may change in the future.
When mailing a letter or package you always use postage purchased in the country you are mailing from. So if you are mailing a letter from the USA to Canada, you would buy stamps at your local post office.
