Between 1710 and 1750, French traders established two trading posts on the Humber River, Magasin Royale, and Fort Toronto. The success of Fort Toronto led the French to build Fort Rouillé on the current Exhibition grounds in 1750. It only lasted until 1759, abandoned after the fall of Fort Niagara, when the French retreated to Montreal. The British arrived the next year with an army to secure the location. The British claimed all of New France after the 1763 Treaty of Paris, and extended the Province of Quebec to present-day Ontario.
