TLD specific


.CA domains can only be registered by Canadian individuals and companies. HEXONET currently does not offer a trustee service.

Please note: Before the migration to a new system on October 12, 2010 it was possible to register provincial third level domain names under,,,,,,,,,,, and CIRA still supports existing domain names, however new registrations are not possible.

Please read the following carefully, as registration of .CA are unique and require care.

1. Registering a .CA domain for a new registrant (contact)

Whenever you register a .CA domain for a new registrant (using a new registrant contact handle) the registrant has to agree to the registrant agreement within 5 days before the domain becomes active. This can be done at providing the contact id of the new registrant. The contact id is returned as property X-CA-CONTACT-REGISTRANT when you perform a StatusDomain command via API or is displayed in our Control Panel at "REGISTRY INFORMATION" for the respective domain.

If you don't activate your .CA domain within 5 days after registration, the domain will get deleted by CIRA.

If the same (already confirmed) registrant contact is used to register another .CA domain then the domain will be registered in real-time.

How can the registrant confirm the registry REGISTRANT AGREEMENT?

As soon as a registration request has been submitted through the HEXONET system, we will send a confirmation email to the email address of the registrant. This email includes a link which redirects to CIRA´s website and also the required "Contact Id", which can be used to confirm the REGISTRANT AGREEMENT. As soon as the registrant has accepted this agreement, the registration of the requested domain name will be processed.

2. Default Privacy of Contact Data and Enabling Disclosure (contact information)

If you register a .CA domain and are a private individual, by default, the registry hides from the public the contact data you provide at the point of registration. For corporations, businesses, and organizations however, the contact data is public by default and is published by the registry.

For those individuals who wish to make public their contact data, the registry allows for disclosure of the information at your request and approval. For any .CA domain name you wish to disclose the contact data, simply check "Disable Privacy" in the respective domain name's Registry Settings through the Control Panel. For API resellers, you can set and/or update the parameter X-CA-DISCLOSE executed through the domain name commands (AddDomain, ModifyDomain).

X-CA-DISCLOSE = 0 | 1 

Support for using the X-CA-DISCLOSE parameter with the contact related commands (AddContact, ModifyContact) stopped on February 5, 2019.

3. Registering a .CA domain for a previously used registrant (contact)

If you register a .CA domain with the same registrant contact that was already used and confirmed for a previously registered .CA domain, then the domain registration is simply processed in real-time. Another confirmation of the registrant contact is not required.

Registration parameters

You always have to state the legal type of the owner. Please find below the possible legal types.

X-CA-LEGALTYPE - required (Legal Types below) 

You can also state the preferred language of the registrant:

X-CA-LANGUAGE - optional registrant contact language ('EN' (default), 'FR')

Trade-mark registered in Canada by non-Canadian owner

In order to register a .CA domain name under the trademark legal type, the trademark must be "registered". Trademarks with a status of "pending" do not qualify.

A Person which does not fall under any other legal type, but which is the owner of a trade-mark
which is the subject of a registration under the Trade-marks Act (Canada) R.S.C. 1985, c.T-13 as
amended from time to time, but in this case such permission is limited to a request to register a .ca
domain name consisting of or including the exact word component of that registered trade-mark.

This legal type is only intended for Registrants which do not meet the requirements
associated with any other legal type but which have a trade-mark registered in Canada.
(Trademarks subject of trade-mark applications and trade-marks registered in other jurisdictions, such
as the United States, do not qualify.) The domain name to be registered must include the trademark.
(i.e. If the trade-mark is AVEA this type of Registrant can register or
but not

The Registrant’s name must be the complete legal name of the trade-mark owner (not the trademark
agent) holding the domain name registration without any abbreviations. (A common
abbreviation may follow the complete name in parentheses.) The applicant must also insert the
Canadian registration number of the trade-mark following the Registrant name.

A valid registrant name would be "Arcuros SPA - TMA1762466"

Partnership Registered in Canada

If the Registrant is a registered Partnership, you should be creating the Registrant using the "PRT"
(Partnership Registered in Canada) legal type.

Please note that the Registrant name must be the registered name of the partnership that will hold the
domain name registration. The Registrant name must also be followed by the jurisdiction of registration.

Examples of VALID Registrant names for the legal type 'Partnership registered in Canada':

John Doe, LLP (Ontario)
Xenon Partnership (Ontario)
Doucett, Entwistle and Theedom LLP (Ontario)
John Doe Partnership, British Columbia
Rosa, Edward, Kelly, Partnership-Ottawa

Examples of INVALID Registrant names for the legal type 'Partnership registered in Canada':

Mybusiness Inc.
Fred Smith
John Doe Partnership

Domain Modification

The registrant of a .CA domain can not be updated within the first 5 days after the successful registration.
If the registrant contact or the administrative contact is being replaced the registry sends an email to the registrant and administrative contact even if the contact information stays unchanged.

Authorization Code

The Authorization Code of a .CA domain may have a length from 6 to 16 characters and may consist of the following characters: a - z, A - Z,0 - 9


After registration, there is a 65-day transfer lock on the domain.

After transfer, the registry applies a mandatory 60-day transfer lock to the domain. This status is automatically removed after the 60 day period has ended.



Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
