Perhaps I can start, Mr. Masse.
From PIAC's point of view, we believe that the speed of unsubscribing should be equal to the speed of subscribing. That was a submission we made in the PIPEDA five-year review.
I think the 31 days is being mentioned because the e-mail instantly gets sent out to other channels of marketing. Specifically in telemarketing, under the “do not call” list, you do have to give the telemarketers 31 days to clear the list. So I think they're trying to line it up with that.
But from our point of view, we take the same position: if I subscribe instantly, and I start getting e-mails right away, I should be able to unsubscribe in a similar time period. We're doing it by the same mode. I'm allowed to unsubscribe by e-mail, so why not by the same amount of time?
