The Bank of Ottawa was absorbed by the Bank of Nova Scotia in 1919, making all surviving chartered bank notes from its final years relatively short-lived issues. By 1913, Canadian chartered banks were already operating under pressure from the 1913 revision of the Bank Act, which tightened reserve requirements and accelerated the consolidation that would eventually end private note issue in Canada altogether.
