smallest municipalities of Metropolitan Toronto were merged into their larger neighbours, resulting in a six-municipality configuration that included the old City of Toronto and the surrounding municipalities of East York, Etobicoke, North York, Scarborough and York. In 1998, the metropolitan government was dissolved by the Provincial Government in the face of vigorous opposition from the smaller component municipalities and all six municipalities were amalgamated into a single municipality, creating the current City of Toronto, with Mel Last man as its first mayor (after being mayor of North York). David Miller was the second mayor and Rob Ford is the third and current mayor.
The city celebrated its 175th anniversary on March 6, 2009, since its inception as the City of Toronto in 1834. Toronto hosted the 4th G-20 summit during June 26–27, 2010, for which the largest security operation in Canadian history took place amidst large-scale protests. Toronto will host the Pan American Games in 2015
