The 1937 Canadian banknote series is the second series of banknotes of the Canadian dollar issued by the Bank of Canada. The banknotes were issued into circulation on 19 July 1937, at which time the Bank of Canada began gradually removing banknotes from the 1935 series from circulation. The $1000 banknote was issued several years later, as it was primarily used by chartered banks, which had a sufficient supply of the 1935 Series $1000 banknote.
