The cost of mailing a first-class letter within Canada is going up Monday by 35 per cent.
Canada Post is raising the price of a stamp to 85-cents, up from 63-cents.
While the new price applies when buying stamps in bulk, it will cost $1 to buy a single first-class stamp.
Canada Post says permanent stamps, which are marked ``p'' will continue to be accepted even though they were bought at the lower price.
Canada Post announced the price hike in December, at the same time it also revealed plans to phase out door-to-door mail delivery to the one-third of Canadian homes that still receive it.
