To register a ".ca" domain, applicants must demonstrate a Canadian presence, which helps to ensure that the domain is associated with Canadian entities. The ".ca" domain is managed by CIRA (Canadian Internet Registration Authority), which oversees the registration process and maintains the integrity of the domain. This domain is popular among Canadians as it signifies a local presence and can enhance trust among users looking for Canadian content or services online.
