The federal Crown corporation wants to raise the prices of Canadian and U.S. stamps bought in booklets, coils or sheets for most letter mail weighing 30 grams or less.
If approved, the increase would mean each domestic stamp would cost 90 cents — an increase of five cents — as of Jan. 11.
The hike would not apply to single domestic stamps, which cost $1.
U.S. stamps would increase to $1.25 from $1.20, while stamps for other international destinations would go to $2.60 from $2.50.
Canada Post says it also plans to increase domestic rates for mail heavier than 30 grams.
It says a full outline of the proposed rate changes will be published Saturday in the Canada Gazette, kicking off a 30-day public consultation period prior to a final decision.
