On March 31, the price of Permanent (or “P”) stamps bought in booklets, coils and panes will be $0.85 per stamp, up from $0.63 today. “P” stamps are valid on standard letters 0-30 g mailed within Canada. A $0.22 stamp will be available as make-up postage for 0-30 g letters for those customers who wish to use previously purchased $0.63 stamps. Permanent stamps, identified with the letter P in place of a value, will continue to be accepted even if they were purchased at a lower price prior to the adjustment.
