This list is a complete joke.
First, it is being administered by a telephone service provision company (Bell Canada) rather than an independent third party that does not derive revenue from telephone subscription services. (Is it really in Bell Canada's interest in profits to dissuade its own business customers from using copious numbers of phone lines and copious amounts of long distance?) Whta independent fourth party is going to supervice Bell Canada? The CRTC? Please, let's get serious here.
Second, what most people do NOT seem to realize yet, is that telemarketers and other scam runners can "spoof" the number that shows up in your caller ID just like email spam coming from non-existant addresses. If anyone wishes to keep calling you, all they have to do is spoof their caller ID. It could take forever for Bell Canada to track the offender down.
Third, vast numbers of calls to Canadians originate in the USA, an area where Bell Canada has ZERO jurisdiction. In addition to American companies that can and will ignore such legislation, any Canadian company that wishes to continue to harass Canadians need only outsource its telemarketing efforts to the USA... well... those that haven't already outsourced them to India, etc.
Fourth, one of the biggest exemptions to this DNC list is newspapers calling to sell subscriptions. Oddly enough, the worst offenders, bar none, in Canada, are newspapers. In my case, it's The Globe and Mail. They outsource to some company that calls CONSTANTLY, hangs up CONSTANTLY and in my own experience and opinion, has the usual non-functioning "call-us-back-at-thuis-number-to-have-your-number-removed" system.
