The region is the central section of Southern Ontario, mainly comprising the rural area around Lake Simcoe.
This has traditionally been the most conservative region of Ontario, in sharp contrast to the Greater Toronto Area to the south.

However, due to massive Reform-PC vote-splitting, the Liberals swept the region during the Chrétien era.
