The Treasury Board is a key part of the government in countries like Canada. It is responsible for overseeing the financial management of government departments and agencies. This includes budgeting, spending, and ensuring that public funds are used efficiently and effectively. The board also sets policies related to human resources and administrative practices within the government. By doing so, it helps maintain accountability and transparency in how taxpayer money is managed. The Treasury Board Secretariat supports the board by providing research and analysis to inform decision-making.
