What is WHOIS?

“WHOIS” is a generic term used to describe an online directory service that allows people to look up information about Internet domain names. CIRA maintains a WHOIS look-up directory which permits queries to the .CA Registry database to determine the availability of .CA domain names or to view the administrative contact and technical information provided by Registrants who have registered .CA domain names.

You can use the WHOIS look-up directory to find out whether a .CA domain name is available and to find Registration information for available domain names. Information for individual Registrants (not organizations) is not displayed in the WHOIS. Information of non-individual Registrants, such as corporations, is displayed by default, although it may not be displayed in special circumstances.

Contacting Individual Registrant Procedures

If you wish to contact a Registrant whose information is not displayed in the WHOIS, you may use the online Message Delivery form. The message is forwarded to the Registrant’s Administrative Contact email address as provided by the Registrant. CIRA cannot guarantee that messages will be received, read and/or responded to by the recipient.

Legal

With respect to certain, specific disputes that a user has not been able to resolve through the Message Delivery form, if such user wishes to contact the Registrant directly to resolve the dispute, CIRA may, under specific and limited circumstances, disclose certain specific contact information of Registrants that is not publicly available through the WHOIS search tool, via the Request for Disclosure of Registrant Information - Rules and Procedures

Law Enforcement

With respect to Canadian law enforcement agencies and the conduct of certain types of investigations, CIRA may also, under specific and limited circumstances, disclose certain specific contact information of Registrants that is not publicly available through the WHOIS search tool via the Request for Disclosure of Registrant Information for Law Enforcement - Rules and Procedures
