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.
Oakwood–Vaughan
Oakwood–Vaughan has changed political boundaries on several occasions. One of the most significant changes was the result of amalgamation in 1998. Formerly part of the City of York, York became part of the City of Toronto, along with Etobicoke, Scarborough, and North York—all cities in their own right before January 1, 1998.
