The gold standard was temporarily abandoned during the First World War and definitively abolished on April 10, 1933. At the outbreak of the Second World War, the exchange rate to the U.S. dollar was fixed at C$1.10 = US$1.00. This was changed to parity in 1946. In 1949, sterling was devalued and Canada followed, returning to a peg of C$1.10 = US$1.00. However, Canada allowed its dollar to float in 1950, whereupon the currency rose to a slight premium over the U.S. dollar for the next decade. But the Canadian dollar fell sharply after 1960 before it was again pegged in 1962 at C$1.00 = US$0.925. This was sometimes pejoratively referred to as the ``Diefenbuck'' or the ``Diefendollar'', after the then Prime Minister, John Diefenbaker. This peg lasted until 1970, after which the currency's value has floated.

has the canadian dollar ever been higher than the us dollar?
