It's not a matter of how many stamps. Stamps come in different values (denominations), just like coins. It's like asking how many coins a candy bar costs. The question is how much postage. You can send an ordinary first-class letter to Canada from the U.S. for 69 cents.
The number of stamps must equal the amount of postage. The postage depends on the weight and and form of transport.
75 cents is the cost of sending an ordinary letter to Canada from the US.
