General Information

The President of the Treasury Board tables three Supplementary Estimates usually in late spring, late fall and early spring to obtain the authority of Parliament to adjust the government's expenditure plan, as reflected in the Estimates for that fiscal year. Funding for these Estimates is provided for in the federal Budget and is, therefore, built into the existing fiscal framework.

The Supplementary Estimates serve two purposes. First, they seek authority for revised spending levels that Parliament will be asked to approve in an Appropriation Act. Second, they provide Parliament with information on changes in the estimated expenditures to be made under the authority of statutes previously passed by Parliament.
