To be truthful, that one has always bothered me
With CIRA if you have the same email address it will show all your domains in your CIRA control panel.
I have never been able to have all my .ca's in one place there because over the years I have had a number of email addresses. The current one (hopefully the last) sales(at)mapledots.ca is the one I would like to use but locking so many domains for 60 days is not an option and could adversely affect a sale.
I wish there were a way around this.
