In 1946, Canada's currency situation was defined by its position within the Bretton Woods international monetary system, established in 1944. The Canadian dollar was fixed to the U.S. dollar at a rate of 1.00 CAD = 0.90 USD, which in turn was pegged to gold at $35 per ounce. This arrangement provided stability and predictability for post-war reconstruction and trade, primarily with the United States, which had become Canada's dominant economic partner. Domestically, the Bank of Canada, nationalized in 1938, managed monetary policy, but its tools were constrained by the fixed exchange rate, which prioritized maintaining the peg over independent domestic interest rate adjustments.
However, significant pressures were building beneath this stable facade. The post-war economy was experiencing strong inflationary pressures due to pent-up consumer demand, the transition from wartime to peacetime production, and global shortages of goods. This created a policy dilemma: raising interest rates to combat inflation would attract foreign capital, putting upward pressure on the Canadian dollar and threatening the fixed parity. Furthermore, Canada was accumulating large U.S. dollar reserves through trade surpluses and capital inflows, which complicated monetary management and fueled domestic money supply growth.
These mounting contradictions led to a historic policy shift. In July 1946, after careful consideration, the Canadian government made the unprecedented decision to
float the Canadian dollar, becoming the first major country to do so within the Bretton Woods framework. This move was a pragmatic response to the unique pressures of the Canadian economy, allowing the Bank of Canada greater autonomy to address inflation without being bound to defend a specific exchange rate. The 1946 float set a precedent for Canada's often-independent approach to monetary policy in the decades that followed.
