The official country-code top-level domain (TLD) for Canada is represented by .ca. The Canadian Internet Registration Authority (CIRA) regulates .ca domains. Anyone registering a .ca domain must meet certain Canadian Presence Requirements (CPR).
Canadian citizens living outside of Canada can register a .ca domain by providing their current address, wherever that may be. Registrants with addresses outside of Canada must provide an up-to-date email address in case the .ca registry needs to get in touch with you.
CIRA enforces a Canadian Presence Requirement or CPR. CPR requires that every registrant select one of eighteen categories to show their connection to Canada. For more information, please refer to What is Registrant Information Validation (RIV)?
When purchasing your .ca domain name, you must specify the correct contact information (including the additional registrant contact details) to complete the domain registration.
Certain country codes, like .ca, require extra information.
The additional registrant contact details include the following:

1. Registrant type, which should be one of the following:
