I didn’t know this until recently, but there is a national do-not-call list you can register your canadian phone number to through the government of Canada:
Additionally, if you’re already a customer with the company calling or have been within a year, they are allowed to call you; HOWEVER,
Next time a company – like rogers for example – incessantly calls you, ask them to add you to their internal do-not-call list, and enjoy your peace knowing that if they call you again, you can report them to the government of Canada. They face possible financial repercussions if this happens.
I’m not sure. I just remember that after it was announced, people signed up, and their spam calls increased. Then any discussion around it disappeared.
I’ll look into it, thanks!
