The Dominion Bank was a Toronto-chartered institution founded in 1871, and its early twentieth-century note issues were handled entirely by the American Bank Note Company — a common arrangement for Canadian chartered banks of that period, when domestic printing capacity was limited and ABNC's security engraving work was trusted across the continent. The Ottawa designation refers to ABNC's Canadian plant, established to serve the chartered bank market without the tariff complications of cross-border shipment.

Chartered bank notes in Canada remained legal tender for private-sector exchange until the Bank of Canada Act of 1934 finally phased them out, making issues like this one functional currency for over three decades after printing.
