I think that Mr. Giguère has raised an important concern about the system, which is that everyone must pay their fair share of tax. As for people with high incomes, I would simply like to mention that those who are in the highest tax bracket, which is 29% at the federal level, represent 3% of the Canadian population, but they pay 35% of the income tax. I would also like to add that every year, the department takes a close look at things in order to ensure that the system is fair. And with every budget, we list what we call the integrity measures that were established by the government.
