Fort Toronto
Fort Toronto was the second of three fortifications the French built in Toronto. Le Magasin Royale was built in 1720 by order of the Governor, Marquis Philippe Rigaud de Vaudreuil, near Baby Point, about north of the mouth of the Humber River. Fort Toronto was built on the eastern bank of the mouth of the Humber, in what would eventually become Swansea, Ontario, by Chevalier de Portneuf between 1830 and 1740.
The French abandoned its fortifications north of Lake Ontario in the 1750s, during the Seven Years' War, known by Americans as the French and Indian War, but it is was renovated and repurposed as a fur trading post by Jean-Bonaventure Rousseau, after Great Britain captured Quebec City and the entire French colony of New France.
