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.
The Annex
European settlement of this area began in the 1790s when surveyors laid out York Township. The area east of Brunswick Avenue became part of the village of Yorkville, while the region west of Brunswick was part of Seaton Village. In 1883, Yorkville agreed to annexation with the City of Toronto. In 1886, Simeon Janes, a developer, created a subdivision which he called the Toronto Annex. The Annex area became part of Toronto in 1887 and Seaton Village joined Toronto in 1888.
