The Bank of Montreal was already Canada's oldest chartered bank when this note was issued, and by 1862 it had long been printing through American Bank Note Company in New York — a common arrangement for colonial and early Canadian institutions that lacked domestic security printing infrastructure of comparable sophistication. ABNC's engraving quality at this period was among the finest available anywhere, and the bank leaned on that relationship consistently through the mid-nineteenth century.
