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.
History of York
The history of York as a city dates to the beginning of the first millennium AD but archaeological evidence for the presence of people in the region of York dates back much further to between 8000 and 7000 BC. As York was a town in Roman times, its Celtic name is recorded in Roman sources (as "Eboracum" and "Eburacum"); after 400, Angles took over the area and adapted the name by folk etymology to Old English "Eoforwīc" or "Eoforīc", which means "wild-boar town" or "rich in wild-boar". The Vikings, who took over the area later, in turn adapted the name by folk etymology to Norse "Jórvík" meaning "horse bay." The modern Welsh name is Efrog.
