Region Overview

Northwestern Ontario (the Northwest) consists of the districts of Kenora, Rainy River, and Thunder Bay, which is roughly the area north of Lake Superior stretching from the Wawa area in the east and the Manitoba border in the west. The region accounts for approximately 60 per cent of the land area in the province and approximately two per cent of Ontario’s total population. Roughly half of the population in the Northwest resides in the city of Thunder Bay and the remaining population resides in smaller communities across the region.

This region is divided into Greenstone-Marathon, North of Dryden, West of Thunder Bay and Thunder Bay sub-regions.
