Country Code

Overview

The Canadian Internet Registration Authority enforces Canadian Presence Requirements on every .ca registration: an applicant must be a citizen, a permanent resident, or an entity constituted in Canada. That gatekeeping is the source of the extension's domestic credibility, since a .ca address signals a verified Canadian connection in a way no unrestricted generic can. Approximately 3.3 million domains sit under the country code, which was delegated in 1987 and is signed with DNSSEC.
