I want you to research into the venues of where a registrar of .ca domain names would offer their business for sale for any reason (bankruptcy, urgent sale, etc...). Information is hard to find so use extensive resources.
Price is $30, if you find many venues and listings I'll offer $50.
Word document, list website, newspaper, personal ad, anything, plus link or phone number. You are free to inquire individually if you want (call registrars to find such leads).
