Letter-post (U.S.A. and International)
What Is Letter-post (U.S.A. and International)?
Letter-post is the most economical method of sending personal and business correspondence to the United States and international destinations. Letter-post items are composed of paper or other material with the general characteristics of paper (e.g., tickets, photographs, etc.). These items must meet the requirements for Letter-post, including size and weight.
Letter-post must be posted in Canada for delivery outside of Canada. Letter-post items can include:
- other paper that meet these specifications which the Customer chooses to deposit.
Standard letters, cards or postcards that weigh 50 g or less and that meet the criteria for standard letters, cards or postcards are mailed at Standard Letter-post prices.
Other Letter-post differs from Standard Letter-post only in terms of weight or size. Items over 50 g and up to 500 g, or items with any dimension over the maximum dimensions of Standard Letter-post are considered Other Letter-post.
A self-mailer is any item other than a postcard, magazine or catalogue that does not have an outer cover, wrapping or envelope (other than the paper or material it has been written on), and weighs up to 50 g.

Labels and Documentation Required
Commercial Customers may prepare an Order (Statement of Mailing) electronically, using the EST software, or manually, using a hard copy Order (40-076-705). A processing fee applies to all manually-prepared Orders.
Two paper copies of the electronic Order, or the original hard copy Order, must be given at the time of mailing to an authorized Canada Post employee at the Receipt Verification Unit (RVU) or at the postal facility approved by Canada Post.
Letter, cards, postcards and envelopes – All letters, cards and postcards must be rectangular and all envelopes including self-mailers and transparent plastic envelopes (also referred to as polybags), must be fully sealed. In order to meet this requirement, irregularly shaped cards or postcards must be sent in a sealed, rectangular envelope.
All letters and postcards must bear the words “AIR MAIL” and/or “PAR AVION” in black or blue on the address side of the item, in the upper left-hand corner, under the return address (when provided). The words “AIR MAIL” and “PAR AVION” can also be printed on a black or blue label, affixed in the same location.
The maximum length to height ratio of letters, cards and postcards is 2.6 : 1. The minimum is 1.3 : 1 to the U.S.A. and 1.4 : 1 to other international destinations. Items paid by postage stamps that do not meet the ratio but fall within maximum standard sizes are charged at the Standard Letter-post price.
Transparent plastic envelopes (also referred to as polybags) – Transparent envelopes can be mailed to U.S.A. and all international destinations. If the plastic is such that it cannot be written upon, the plastic film must have a 20 mm-wide white opaque band, large enough to hold the mailing address, postage and service instructions. If the closed transparent material can be written upon, a sample of the envelope must be submitted for testing and approval by Canada Post.
Window envelopes – Window envelopes are acceptable only if the window has a transparent cover parallel to the length of the envelope and the mailing address, which must be easily read, and not interfere with the date-stamping process.
Postcards – Postcards may have an illustration, stamp, label or address slip attached, provided it is made of paper, is very thin, and sticks completely to the postcard. These items must be stuck to either the front of the postcard or the left-hand portion of the back. The right-hand half of the back must be used for the addressee, service instructions and postage. The word(s) “POSTCARD” or “CARTE POSTALE” must appear on the address side of all postcards (except on illustrated and picture postcards).
Addresses must be legible and complete. See Addressing Guidelines for complete details.
There must be only one return address on each item of Letter-post (U.S.A. and International), and if used, that return address must be Canadian.
