After a period of a floating exchange rate in the 1950s and early 1960s, Canada fixed the Canadian dollar at 92.5 U.S. cents (with a narrow fluctuation band). This peg limited how independent Canadian interest-rate policy could be, because Canada needed to defend the fixed rate against market pressure. It set the stage for later tensions when inflation, capital flows, and commodity prices pushed the currency away from the peg.
Canada ended the fixed-rate system and allowed the Canadian dollar to float—meaning its value was set mainly by foreign-exchange markets rather than by a government peg. Bank of Canada analysis points to strong upward pressure on the dollar from commodity prices and capital inflows, and concern that defending a peg would add to inflation risks. The decision marked the start of the modern floating era that shaped currency volatility through the 1970s and 1980s.
Once floating, the Canadian dollar strengthened and moved up toward parity with the U.S. dollar. This reflected strong demand for Canadian exports and assets, and shows how a float can quickly pass through new economic information into the exchange rate. The episode also helped cement the idea that the exchange rate would act as a key “adjustment” price for Canada going forward.
In spring 1974 the Canadian dollar rose above the U.S. dollar, reaching about US$1.0443. This high point illustrates how a floating currency can swing with global conditions, including commodity cycles and international capital movements. It also became a reference point for later comparisons when the dollar weakened in the 1980s.
The election of the Parti Québécois government introduced a major new political uncertainty for investors, tied to the possibility of Quebec sovereignty. Even under a floating exchange rate, expectations and risk perceptions can move the currency because they affect capital flows and the demand for Canadian assets. This period helped connect exchange-rate volatility to political events as well as to trade and commodity prices.
Quebec voters rejected the sovereignty-association proposal in a May 1980 referendum. The vote reduced one source of political uncertainty, but it did not remove broader economic pressures affecting the currency, such as inflation and shifting commodity markets. The event matters in this timeline because it shows how domestic political risk could become tied to the floating dollar’s ups and downs.
The federal government introduced the National Energy Program (NEP) on October 28, 1980, aiming at energy security, revenue-sharing, and greater Canadian ownership in the oil sector. Because energy exports and investment were central to Canada’s external balance, major policy shifts in the sector influenced capital flows and confidence—factors that can feed into a floating exchange rate. The NEP became a lasting symbol of how domestic resource policy could interact with currency movements.
In the early 1980s, Canadian interest rates rose sharply, reflecting the period’s inflation and the effort to stabilize prices and financial conditions. Under a float, higher rates can support a currency by attracting capital, but they can also slow growth and raise recession risks. This era shows how the exchange rate, inflation, and monetary policy became closely linked.
In 1985, the Canadian Commercial Bank and Northland Bank failed, prompting inquiries and reforms aimed at strengthening oversight and stability. Bank failures can affect a currency indirectly by undermining confidence and changing expectations about financial risk. The episode also overlapped with weaker commodity conditions and a softening Canadian dollar, reinforcing the sense of vulnerability in the mid-1980s.
On February 4, 1986, the Canadian dollar dropped below 70 U.S. cents, hitting a record low level reported at the time. The decline highlighted how a floating currency can adjust quickly when markets see weak economic prospects or unfavorable terms of trade (the prices Canada gets for exports relative to imports), especially for a commodity exporter. It also intensified debate over whether policy should react to defend the currency or prioritize domestic goals like growth and inflation control.
Canada and the United States signed the Canada–U.S. Free Trade Agreement in early 1988 after negotiations concluded in 1987, and it took effect in 1989. By deepening cross-border trade and investment ties, the agreement increased the importance of the Canada–U.S. exchange rate for many businesses, even though the dollar remained floating. Over time, greater integration also meant that shocks in the U.S. economy could transmit more directly into Canadian trade flows and currency markets.
In February 1991, the Bank of Canada and the federal government announced formal inflation-control targets. This policy shift helped define the “closing outcome” for the 1970–1990 floating era: instead of trying to manage the exchange rate directly, Canada increasingly used monetary policy to control inflation while allowing the currency to float and absorb shocks, including commodity-linked swings. The framework became a cornerstone of Canada’s modern monetary system.
