Amendments to Canada Post Regulations

Summary#

This is a proposed, technical set of amendments published on June 20, 2026 to update regulations made under the Canada Post Corporation Act after the federal government changed the law in the Budget 2025 Implementation Act, No. 1 (Bill C-15). The changes mostly remove old rules that referred to “regulated” postage rates and preserve size and weight limits for different mail categories; stamp prices themselves do not change.

What it does#

• Removes references to regulated postage rates that will no longer apply once the legislative change in Bill C-15 takes effect.
• Repeals or edits parts of several regulations, including:
  • International Letter-post Items Regulations — repeals section 4 and Schedule IV.
  • Letter Mail Regulations — repeals section 3 and the Schedule; updates rules so size and weight limits remain in the regulations (for example, an envelope is exempt from the sealing rule if it is more than 245 mm long, 156 mm wide, 5 mm thick or weighs more than 50 g).
  • Special Services and Fees Regulations — repeals section 2.1 and Schedule VII; removes subsection 6(1); replaces subsection 6(10) to require that if adhesive tape is used to close an item the sender must put their name, mark, stamp or signature on the tape.
  • Armed Forces Postal Regulations — repeals section 4, subsection 7(2), and the schedule.
• Fixes related French-language wording for size limits (including 380 mm, 270 mm, 20 mm, 140 mm, 90 mm, and 0.18 mm where they appear).
• These are proposed regulations (not final). The public can make written comments within 30 days of the notice.

Who's affected#

• People and businesses that send letter mail or use special postal services in Canada.
• Canada Post Corporation, which will no longer be required by statute to get Governor in Council approval for postage rate changes (that change comes from the legislative amendment in Bill C-15; these regulatory edits are housekeeping to match that law).
• The Armed Forces and users of military postal services (because related rules are being removed or updated).
• The government says the changes will not increase costs or regulatory burdens and will not affect small businesses under the small business lens.
• Members of the public or organizations that want to comment should send representations within 30 days to Krista Leben, Director, Regulatory Affairs, Canada Post Corporation (contact details are in the notice).

Why it matters#

• This is mainly housekeeping: it clears out regulatory language that would become obsolete after the law changed about how postage rates are approved.
• There is no immediate change to stamp prices — the notice says stamp rates remain the same and can be viewed on Canada Post’s website.
• In practical terms, the legislative change behind these amendments means future postage-rate changes will no longer need Governor in Council approval, which could make the timing and process for rate changes different in the future.
• The proposed edits also make sure basic size and weight rules for different mail types stay in force so mail is still categorized consistently.
