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.
Metropolitan Street Railway (Toronto)
On August 16, 1922, the City of Toronto formally acquired the T&YRR lines. The plan was that the city portions of the T&YRR radial lines would be incorporated into the TTC, and the portions outside the city would be managed by Ontario Hydro as the Hydro-Electric Railways: Toronto and York Division. 
On November 1, 1922, Hydro-Electric Railways took over operation of the T&YRR lines outside of the city limits. Hydro initiated a number of line improvements including track rehabilitation, a new station at Schomberg Junction, new waiting shelters, more passing sidings and additional service to Thornhill and Bond Lake Park.
