Our domain registrar partner, Wild West Domains, does not offer .CA domains through their api so we are not able to register a .CA domain name.
You can register your .CA domain at a registrar such as GoDaddy.com and then point it to your FASO website by changing the domain nameservers (DNS) to ours. Your domain will then pull up (point to) your FASO website.
There is no charge to point a domain.
You will of course, be liable for the fees that your domain registrar charges for the domain.
For the steps on how to point a domain, see this FAQ:
Can I use my existing domain name?
