It would be the Chief Electoral Officer.
You see, under the statute now, under the Canada Elections Act, if you intend to spend more than $500 in advertising, you have to register. If you don't, you're breaking the law. People will see that you're doing ads, and one thing I really liked is that Canadians watch the system. When I was in charge, they would write and complain. We had 500 written complaints at every election. They watch. They watch what you report in your expenditures. They watch when events are being held and they ask if this event was reported or not. Some of it is for political reasons; some of it is purely out of concern for the integrity of the system. It was really quite gratifying to see that.
