We also have to involve some of the domain owners who collect a just few domains.
You do not have to be a domainer full time, it could be a little hobby and one could own just a few domains.
There is no set criteria to join and a lot of people own a few domains they are proud of.
I am only half-kidding. Would be interesting to know how many individuals in Canada own 10 or more domains. I think it would be a relatively small number. Domaining still seems to be a niche thing after all these years, judging by how often it comes up in everyday conversation with people I know. The idea of having a personal domain for your email, for example, even just to forward it, isn't done by most people. They just rather use gmail, shaw, icloud, telus, etc.
