I'm sure you understood correctly.
I am proposing to expand the mandate of the Parliamentary Budget Officer to include the systematic long-term analysis of government estimates, which are tabled before March 1st of every year. I am talking about all the estimates for a given year, including supplementary estimates which are tabled in the fall. The latter are the result of various bills that have already passed, legislation supporting new programs and initiatives that the government may have announced in the previous budget.
Therefore, my suggestion is not with regard to bills as such, but rather the analysis of the budgetary estimates themselves.
