I cannot see the whois info for my .ca domain

The latest CIRA policy is that any modification to the whois info for .ca domain names is visible only on the specific registrar WHOIS lookup.

The WHOIS details change can not be performed more often that 60 days.

Thus any contact details won't be visible on the global WHOIS search engines.

If you are a SiteGround customer and you wish to make changes to the WHOIS information for your domain, you can do so via the My Accounts section for your User Area with SiteGround clicking the Manage button for the domain name.
