Since 1877
Founded in 1817, Bank of Montreal (BMO) is the oldest legally incorporated bank in all of Canada ??
The Bank of Montreal was established in 23 June 1817,[11] when a group of merchants composed by Robert Armour, John C. Bush, Austin Cuvillier, George Garden, Horatio Gates, James Leslie, George Moffatt, John Richardson, and Thomas A. Turner signed the Articles of Association, formally creating the « Montreal Bank ».
The bank was first located in rooms rented on Rue Saint-Paul, Montreal, before moving to its permanent building on Rue Saint-Paul in 1818.
