WARNING
Though I complained to the Competition Bureau of Canada in April, a company called “Domain Registry of Canada” with a mailing address in Markham, Ontario continues what I consider to be a mail SCAM.
They send people who own domain names (RickMcCharles.com, for example) a “Domain Name Expiration Notice” that looks like a renewal invoice.

I have a copy of their letter scam if you want to see it.
