4 Dollars

The Banque Jacques Cartier was a Montreal commercial bank chartered in 1861, operating through some of the most turbulent years in Canadian banking history before its collapse in 1899. This $4 denomination is a peculiarity worth noting: four-dollar notes were a legitimate fixture of Canadian private banking practice, designed to work alongside the prevailing decimal and pre-decimal coinage in a way that minimized the need for large coin payouts at the till.

The British American Bank Note Company, established in Ottawa and Montreal in 1866, was printing for numerous chartered banks by 1870 and quickly became the dominant security printer in the country — a position it held for well over a century.
