Thank you for the question.
My predecessor, Mr. Vaughan, completed a study on financial subsidies. That was included in our report in February. I am not an expert in this area, but we noted a few points of interest during that study, that is to say regarding most of the subsidies.
I apologize, but I am going to answer in English because I don't know the terminology in French regarding these subsidies.
We concluded that the biggest single subsidy at the moment is the accelerated capital cost allowance. That is being phased out, and the minister did mention that. The two largest ones that remain are tax expenditures. Those are, as was mentioned, the Canadian development—I have my copy in French here, so if I'm totally confused, excuse me—tax expenditure and the exploration one.
One of the things we noted in that study is that while we could put a price tag against the accelerated capital cost allowance, Finance isn't in a position to estimate what the tax expenditures actually cost the Canadian taxpayer. Now, we did note that this is a very difficult area. It is very difficult to estimate tax expenditures, but one of the things we noted was that it is an important part of what the government needs to work on, because that is what remains as two key elements of the support.
