The Do-Not-Call List that I wrote about is going live this morning. You can register by calling the toll free number at 1-866-580-3625 or 1-888-362-5889 (for the hearing impaired). Alternatively, you can also visit their website, LNNT-DCNLgc.ca
Expect to be put on hold for a long time, or a very slow page loading, though. The website and phone lines are overwhelmed.
PS: You might also be interested in ioptout for opting out from hundreds of organizations contacts.
