The Bank of Canada has played an integral role in Canadian society for 70 years. When the Bank opened its doors in the spring of 1935, this country was struggling to define itself and to survive the economic and social turmoil of the Great Depression. Like Canada’s economy, its central bank has evolved and grown over the years. It has faced critical challenges and embraced change. But the Bank’s mandate has not changed. It is now, as it was then, to provide an effective, national monetary authority for Canada.
