Southwestern Ontario
The topography of Southwestern Ontario is primarily characterized by gently rolling terrain, with notable variations due to glacial activity and the influence of major water bodies like Lake Erie and Lake Huron. The region lies within the Mixedwood Plains, a flat and fertile ecozone that was once extensively forested but is now largely used for agriculture. The landscape includes some areas of hilly terrain, especially in regions such as the Niagara Escarpment, which stretches through parts of the region. This escarpment, a significant geological feature, offers steep cliffs and rolling hills, contrasting with the flatter, more agricultural areas to the south and west. Additionally, southwestern Ontario is marked by a variety of landforms shaped by the retreat of glaciers during the last Ice Age, including deep valleys, moraine deposits, and the occasional ridge. The region’s varied topography makes it both agriculturally productive and ecologically diverse.
