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.
Boroughs of Canada
East York, Ontario, although an independent municipality with its own mayor and council, was also formerly designated as a borough. With the community's amalgamation into Toronto in 1998, East York no longer holds this status. At the time, East York was the only municipality in Canada designated as a borough; most of the communities in Quebec now designated as "arrondissements" or boroughs were also independent "villes" prior to 2002.
