The PERMANENT™ stamp, identified with the letter P in place of a value, is always accepted at the current domestic postage price. If you buy a PERMANENT stamp today, you can use it anytime in the future.
One PERMANENT stamp can be used to mail a letter (weighing up to 30 grams) anywhere in Canada. You can also combine PERMANENT stamps with additional postage to mail larger letters, parcels or to send mail internationally.
