The Bank of Canada is Canada's central bank. The four main areas of responsibility for the bank includes monetary policy, which concerns how much money circulates within the economy and how much it is worth, designing, producing, and distributing bank notes as the country's sole currency issuing authority, maintaining the financial system consisting of financial institutions, markets, and payments systems, and funds management as the "fiscal agent" for the Government of Canada.
