I understand, but you are talking about political parties' investment income. It's fine if they decide to make investments or deposit money into an account to get a return. Political parties can manage their coffers as they like. However, we are here talking about public money coming from taxpayers' dollars being used to fund political parties' election activities. What's more, this will lead to additional costs for the government through the chief electoral officer, or CEO. That is duplication of funding because the money filling political parties' coffers will lead to an increase in funding provided by the CEO.
I understand the parallel you made. You are talking about the Bloc Québécois' position. I can tell you that we are very proud not to have taken taxpayers' money. We expect only our sympathizers to fund our election activities. We are confident in them and they in us, obviously.
The current system does not provide for the public funding of political parties. However, the pandemic has led to the appearance of public funding.
Should we question public funding through such misappropriation? We should check what political parties would like to have and how to provide them with public funding, instead of finding roundabout ways to receive funding, which favours parties that do not deserve it.
