In the 1830's to 1860's Provincial and Municipal Governments (and even some cites) in Canada issued notes for themselves.
By 1866 the Federal Government, hugely in debt, implemented government-issued bills in denominations of $1 to $1000. In 1871 the Government started to restrict the Chartered Banks and the lower forms of Government, from issuing their own currency. Initially, this central issuer was called the "Dominion of Canada".
When the Bank of Canada finally came into being in 1935, all "Dominion of Canada" notes where taken over by the new, official central bank.
