I don't think it's feasible or desirable to eliminate either the budget or the estimates.
The budget is a major policy document of intention and action on the part of the government, dealing with its fiscal policy, its expenditures and revenues. It's a comprehensive document that sets out what the government is going to do against the backdrop of its Speech from the Throne and, indeed, its campaign commitments.
The estimates, of course, are the transformation of the government's budget into expenditure programs and into votes for the approval of Parliament.
I think those two documents need and ought to be separate and distinct. My case has been for a greater alignment between the two.
