York North

York North was an electoral district in Ontario, Canada, that was represented in the Canadian House of Commons from Confederation in 1867 until 2004. It is also an electoral district that was represented in the Legislative Assembly of Ontario from 1867 to 2007. The provincial riding was known as York—Mackenzie from 1995 to 1999.

The federal riding was eliminated in 2003 when it was redistributed between two new ridings of Newmarket—Aurora and York—Simcoe. Another small section was incorporated into Oak Ridges—Markham. The riding covered the northern suburbs of the city of Toronto often including such towns as Aurora, Vaughan, Newmarket, Richmond Hill and Markham. The borders changed often, however, most notably in 1996 when the riding was so altered that it contained very little of the same territory as before.

In 2007, the Ontario provincial electoral district was eliminated when it was matched to the redistributed ridings of the federal districts. Julia Munro, who held the York North seat, was re-elected in the new riding of York—Simcoe.
