About .ca

The .ca domain is Canada's country code top-level domain. It is managed by the Canadian Internet Registration Authority, also known as CIRA. .ca domains are subject to a Canadian Presence Requirement, meaning registrants must meet specific criteria such as being a Canadian citizen, permanent resident, or an organization recognized under Canadian law. This rule helps maintain a distinctly Canadian namespace. CIRA took over stewardship of .ca in 2000 after a redelegation from the University of British Columbia. The registry is based in Ottawa and also provides WHOIS and RDAP services for domain lookups.

History

.ca was originally delegated in 1987 to the University of British Columbia. In December 2000, following a formal redelegation process, responsibility shifted to CIRA, a not for profit corporation. This change brought the domain under dedicated Canadian management.

Eligibility & restrictions

Registrants must meet a Canadian Presence Requirement defined by CIRA. This typically includes Canadian citizens, permanent residents, or legally recognized entities in Canada.
