Starting on September 30, 2008, the Government of Canada will FINALLY implement its DO NOT CALL list, making it illegal for telephone solicitors to disturb you with unsolicited sales calls if you have registered on the list. There are some exceptions.
A fact sheet on your consumer rights under the laws of Canada with respect to unsolicited telephone calls can be found at the following link.
Effective September 30, you can register with the Government of Canada on the DO NOT CALL list. A link to that page is also provided at this link.
