Hamilton is located on the western end of the Niagara Peninsula and wraps around the westernmost part of the Lake Ontario. Most of the city including the downtown section lies along the south shore. Situated in the geographic centre of the Golden Horseshoe, it lies roughly midway between Toronto and Buffalo. The two major physical features are Hamilton Harbour marking the northern limit of the city and the Niagara Escarpment running through the middle of the city across its entire breadth, bisecting the city into 'upper' and 'lower' parts.
