When .CA domains are initially registered, CIRA sends an approval email to the registrant email contact. The domain registration is not complete until the registrant approves it via this email.
While in this "pending-approval" status, the domain will not resolve or otherwise function. The domain will appear within your account, but you will not be able to fully manage it, especially at the registry level, until approved.
The registrant has 7 days to approve the registration, otherwise the registration is terminated.
