The cost of registering a  .ca domain name

You must be a legal Canadian resident, Canadian citizen, or a company which has the legal right to do business in Canada. A registered trade mark in Canada is also accepted, but only of the domain name resembles the trade mark.
After you register your domain, you will receive an email from CIRA (the .ca-registry) with your CIRA login and temporary password. You must log into the CIRA site within 7 days to complete the registration of your domain.
During this phase, you will read their terms and agreements and attest that you meet their requirements. Failure to complete this registration during this 7-day period results in the deletion of the domain. CIRA reserves the right request proof of eligibility at any time, and can delete domains if registrants do not meet their terms.
