.ca WHOIS Lookup: CIRA Records and Contact Roles
.ca is the country code extension of Canada and has been in the root zone since 14 May 1987. Its registry is the Canadian Internet Registration Authority, known as CIRA in English and ACEI in French. WHOIS queries go to whois.cira.ca, and CIRA also publishes registration data over RDAP at rdap.ca.fury.ca. DNSSEC protects the .ca zone.
A .ca WHOIS reply holds sixty-seven fields. Besides the creation, update and expiry dates, the registrar with its abuse email and phone, and the status codes, it carries four contact roles: registrant, administrative, technical and billing. Each role has a block of its own with lines for an identifier, name, organisation, street address, phone, fax and email. The line for the registrar's IANA number is present too, but it reads not applicable. To compare with the southern neighbour, open the .us WHOIS lookup.

WHOIS FAQ
Does a .ca WHOIS lookup show who owns the domain?
Yes, on a company-held .ca name the registrant block shows the holder's name, organisation, address, phone number and email, and the administrative and technical blocks are filled in as well. Names registered by private individuals look different, because identity data on personal records is usually closed and only the existence of the role stays visible.
Why does the Registrar IANA ID say not applicable on a .ca domain?
The value reads not applicable because .ca registrars are accredited through CIRA's own programme and therefore carry no ICANN-issued IANA number. The line appears only because the .ca reply follows the same field template as generic extensions. The registrar's name, abuse email and abuse phone still arrive with real values, so the registrar can be identified and reached without the number.
What extra information does RDAP give for a .ca domain?
RDAP returns the .ca record as structured JSON and lists the registrar, registrant, administrative, technical and billing roles as separate entities. On a company record the registrant, administrative and technical entities come with their names. Registration, expiration and last change are given as dated events, which suits software that processes records automatically. To see how a generic extension presents the same roles, open the .biz WHOIS lookup.
Where can I see when a .ca domain expires?
A .ca domain expires on the date shown on its Registry Expiry Date line, given in UTC, and RDAP reports the same date as the expiration event. Creation Date tells you when the name was first registered and Updated Date when the record last changed. The whois.com.tr result screen calculates the domain's age and the time left until renewal from these dates.
What do the status codes on a .ca domain mean?
Status codes on a .ca domain are standard EPP codes, and a company-held name can carry six of them, so deletion, transfer and updates are each locked from both sides. The three beginning with client belong to the registrar, which can remove them itself. The three beginning with server are set by CIRA, and only the registry can lift them.
Can a WHOIS lookup show if a .ca domain is available?
Yes, CIRA's reply makes availability clear. For a name nobody holds, the registry reports that no match was found, none of the record fields appear, and whois.com.tr shows the name as available. If the name is taken, the registrar line in the reply tells you which company manages it.
