The main postal operator in Canada is the Canada Post Corporation, which has a long history dating back to 1867, when it was first established as the Royal Mail of Canada. Later in the 1960s, it was renamed as "Canada Post." The Canada Post Corporation Act officially recognized this transition and dissolved the previous post office, forming the current corporation responsible for postal services across Canada.

The Canada Post Group comprises several companies, including Canada Post, with approximately 64,000 employees. Other companies of interest to the Corporation are Purolator Courier, Innovapost, Progistix-Solutions, and Canada Post International Limited. In 2000, Canada Post launched Epost, a free service allowing customers to receive electronic invoices from participating merchants and institutions.
