As you may or may not know Canada now has a National Do No Call List. So if you're tired of receiving unwanted call from telemarketers you can register your phone number (residential or wireless) with the National DNCL. Keep in mind that those annoying calls won't stop immediately as telemarketers have up to 31 days to update their lists. You may still receive calls within those 31 days.
