The Bank of Montreal was founded in 1817 placing it among Canada's oldest financial institutions. It later merged with the Commercial Bank of Canada in 1868, as well as several others including the Molson Bank in 1925. It was allowed to issue its own currency until the passing of the Bank of Canada Act in 1934.
The bank maintained a library at its head office in Montreal for many years. The bookplate at left depicts the bank's head office located at Place d'Armes in Montreal, and was designed by Canadian artist Stanley Harrod (1881-1954), a notable illustrator of many prominent bookplates during the early 20th century.
Today, the five main banks in Canada are the Toronto Dominion Bank, the Bank of Montreal, Scotia Bank, The Canadian Imperial Bank of Commerce, and the Banque Nationale. If anyone knows of any bookplates belonging to these other historical Canadian banks please get in touch, I'd love to hear about them!
