That is based on the fact that, for a number of years, electoral management bodies, Elections Ontario and Elections Canada, have a great number of historical records and information based on fundraising activities and on the amounts that both candidates and political parties have raised over the years and have spent. We have all kinds of statistics to show what the average political party has spent on a campaign in Ontario over the last 10 to 15 years. There can be some fairly easy analysis done on that to ensure that, whatever model you put in place, it does not unduly enrich political actors.
