If you live in Canada, you can choose to reduce the number of telemarketing calls you receive by registering your residential, wireless, fax or VoIP telephone number on the National Do Not Call List (DNCL). If your telephone number is not linked to a business line, then you are considered to be a consumer for the purposes of the National DNCL.

If you’re a telemarketer, you have to abide by the Unsolicited Telecommunications Rules (UTR), register with and pay to use the DNCL.

You can get more information from the CRTC website: https://crtc.gc.ca/eng/phone/telemarketing/
