The lettermail service allows the transmission of virtually any paper document. The 2015 to 2018 rate was 85 cents for a standard letter (30 g or less) and $1.20 for a letter between 30 g and 50 g. Proposed change for 2019 is 90 cents and $1.27 for these rates. Rates usually increase in mid-January of each year; for ordinary letters (30 g or less).<ref>{{Cite canlaw|link=http://www.canlii.org/en/ca/laws/regusor-88-430/latest/sor-88-430.html#SCHEDULE__23737|linkloc=CanLII|type=reg|regtitle=Letter Mail Regulations|regnumber=SOR/88-430}}. Schedule ("Rates of Postage — Letter Mail") to section 3.</ref>{{Update after|2015|12|01||reason=rates seem to increase every year; check table at bottom of Letter Mail Regulations for the new 2015 rate.}} The rate was regulated by a price-cap formula, linked to the inflation rate.<ref>Under the price-cap formula approved by the federal government in 2000, basic letter rate increases, when warranted, will not exceed 66.67% of inflation as measured by the Consumer Price Index from May prior to the last increase to May of the current year. Increases will be implemented no more than once a year, in January, and announced no later than July 1 in the year before the increase goes into effect in the Canada Gazette Part I.</ref> The Corporation now has a "permanent" stamp that is valued at the domestic rate forever, eliminating the need to buy 1 cent stamps after a rate increase. The rates for lettermail are based on weight and size and determine whether the article falls into the aforementioned standard format or in the oversize one.

From 2015 to 2018, the rate for a standard letter is $1.20 if sent to the United States and $2.50 if sent to any other destination.<ref>{{cite web|url=http://www.canadapost.ca/cpo/mc/business/productsservices/letterpost.jsf|title=Postes Canada – Poste aux lettres à destination des États-Unis et du régime international|access-date=2014-01-07|url-status=dead|archive-url=https://web.archive.org/web/20130521232244/https://www.canadapost.ca/cpo/mc/business/productsservices/letterpost.jsf|archive-date=2013-05-21}}</ref>
