As many of the wealthy French Canadians moved from Canada to France following the Conquest, British merchants were able to cheaply purchase vast tracts of land upon which to build factories, and take control of the banking and finance of the new Dominion. The growing fortune of the Montreal mercantile elite of this era was consolidated through marriage and company mergers. After the collapse of the fur trade in the 1850s, the mercantile elite turned its interest to railways and shipping.
