I might start by saying that there was a task force working group originally on the Task Force on Spam in 2005 that tried to have a wide reach to get at this issue. It included.... I'll just note that the co-chairs were Roger Tassé and Michael Geist, but the member organizations were a broad range that included the Coalition Against Unsolicited Commercial Email, Amazon, Bell Canada, the office of consumer affairs, the Privacy Commissioner, and PayPal. All of these I think indicate that there is wide interest in the legal, academic, consumer, and commercial zones that rely upon this legislation, all of which have views, certainly.
