This is $1 billion, not $4 billion. It is not 1% of the total debt. Thank you.
This next question is mainly for information. I wasn't here at the beginning of your presentation.
How does it work for the budget process? We had the Canada Revenue Agency and had different numbers thrown at us on the costs whenever there's a change in policy, such as when the tax rates go from 15% to 16%, or from 16% to 15% and 15.5%. The one that we had questions on was the GST, when the GST is reduced from 7% to 6%.
I'm a bit worried. If you're not talking to a department like the Revenue Agency and trying to determine how much it's going to cost, I wonder, with all these measures when you're preparing a budget, how much it really costs to implement some of these measures, especially some of these superficial ones where we're giving back $80 for books and public transit and things like that.
