$1.20 is the current price for a Global Forever stamp. That will cover you for a 1 oz letter, or postcard, to Canada or any other foreign country. Some greeting cards these days run more than 1.0 oz; you need to pay about a dollar more for the second oz or fraction thereof. Except for Canada--the Global Forever stamp is enough postage right thru 2.0 oz. It's okay to use other stamps that equal the current price of a Global Forever. Extra charge for non-machinable international (must still be 1/4' or less) is .21, one penny more than with a domestic letter.
International letters are $1.20
I believe canada is the same as the standard state rate
