Sending mail just got a little more pricey.

Starting today, Canada Post is increasing its postage rates from $1.15 to $1.44 for the price of a single domestic stamp.

For stamps purchased in a booklet, coil or pane—which the postal service says represents most stamp sales—the rate has increased by 25 cents to $1.24 per stamp.

"Today's rate change represents a one-time increase of roughly 25 per cent, which is required to better align stamp prices with the rising cost of providing letter mail service to all Canadians," reads a statement from Canada Post.

"Every year, there are fewer letters to deliver to more addresses, which adds significant cost pressures to the Corporation on top of continued inflationary pressures."

The Crown corporation says the estimated impact of this rate hike is $2.26 per year for the average Canadian household. The estimated impact for the average Canadian small business is $42.17 per year.

The price increase was announced in September 2024. It received final regulatory approval in late November.

"As an organization funded by revenue from the sale of its products and services – not taxpayer dollars – rate changes are a reality," said Canada Post.

The price hike also affects other products, including US, international letter-post and domestic registered mail items. The postal service says that commercial letter mail price changes, which are also effective today, correspond to the increase in the regulated letter mail rate.

The last Canada Post stamp price increase was in May 2024. Stamps in a booklet, coil, or pane increased by seven cents to 99 cents per stamp. The price of a single domestic stamp was bumped from $1.07 to $1.15.

Last week, the postal service announced that it is back to full-service levels for domestic parcels after the Canadian Union of Postal Workers' (CUPW) month-long strike in November.
