Ontario is a province in east-central Canada that borders the U.S. and the Great Lakes. It is sometimes conceptually divided into two regions, Northern Ontario and Southern Ontario. The great majority of Ontario's population and arable land is in the south. In contrast, the larger, northern part of Ontario is sparsely populated with cold winters and heavy forestation. The varied landscape includes the vast, rocky and mineral-rich Canadian Shield, which separates the fertile farmland in the south and the grassy lowlands of the north.

Ontario’s forests play a major role in the province’s economy. They contribute to a good standard of living by supporting more than 53,000 direct jobs in the forest industry (2011). In total, the forestry sector supports almost 200,000 direct and indirect jobs across 260 Ontario communities.
