I indicated that I'm comfortable with the duration of the present limits. There's an issue that needs to be borne in mind, which is that, if you were to extend it further backwards, you risk running into a parliamentary session. That was an issue when British Columbia tried to bring in some limits about 10 years ago. They said that could create a chill while the legislature was in session. In other words, members would be making speeches, talking to the media, but third parties would be prevented from undertaking any direct advertising during that period. I think that the drafting of the bill must have taken that into account.
