Municipal government of Toronto
On January 1, 1967, several of the smaller municipalities were amalgamated with larger ones, reducing their number to six. Forest Hill and Swansea became part of Toronto; Long Branch, Mimico, and New Toronto joined Etobicoke; Weston merged with York; and Leaside amalgamated with East York. This arrangement lasted until 1998, when the regional level of government was abolished and Etobicoke, North York, East York, York, and Scarborough were amalgamated into Toronto the "megacity". Mel Lastman, the long-time mayor of North York before the amalgamation, was the first mayor (62nd overall) of the new "megacity" of Toronto, which is the successor of the previous City of Toronto.
York, Upper Canada
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.
