.ca (Canada) Registered Domain Names List Download / .ca zone file

.ca is the Internet country code top-level domain (ccTLD) for Canada. The domain name registry that operates it is the Canadian Internet Registration Authority (CIRA).

Registrants can register domains at the second level (e.g., example.ca). Third-level registrations in one of the geographic third-level domains defined by the registry (e.g. example.ab.ca) were discontinued on October 12, 2010, but existing third-level domain names continue to be supported.

Internationalized domain names (IDN) were introduced in January 2013 with a limited selection of characters (é, ë, ê, è, â, à, æ, ô, œ, ù, û, ü, ç, î, ï, ÿ) to allow French language text withdiacritics. Names which differ only in diacritical accents (such as metro.ca and métro.ca) must have the same owner and same registrar. Domain names that begin with the four charactersxn-- are otherwise not available for registration. Length must be 2-63 characters, including the xn-- prefix encoding for internationalised domain names.


Names which match the name of an existing generic three-letter top-level domain (such as .com.ca) or the Canadian top level country code (.ca) are reserved and therefore not available for new registrations. Certain expletives are not accepted as names. Municipal names of individual cities and localities within Canada are also reserved nationwide, along with village.ca, hamlet.ca, town.ca, city.ca, ville.ca and the names of Canadian provinces.

There are a handful of existing .ca registered names as short as two characters in length, but these tend to be rare as two-letter combinations matching any existing country-code TLDs were reserved in the past. Exceptions were typically names registered before the restriction was introduced, such as the Canadian Governor General at gg.ca.
