I don't know if the chances of the robocall are greater, but I think what is true is that the likelihood of a voter fraud campaign coming to light is much less likely because the people who would know that it has taken place are muzzled under the bill.
It's not just the Chief Electoral Officer under section 18. You actually have to look at proposed subsection 510.1(1) as well, because the commissioner is precluded, arguably, from allowing an ITO filed in a court to be filed in any other way but under seal, which would mean that the discovery that Mr. Maher and Mr. McGregor made of an ITO filed in Edmonton in November 2011 would never have been known. This bill probably wouldn't be before us and no one would know that there was voter suppression during 2011 under these new rules.
