01 · OverviewGreater Sudbury, in brief
Greater Sudbury is the most populous city in Northern Ontario, Canada, with a 2021 census population of 166,004. It functions as the sole single-tier municipality in Northern Ontario, standing as the largest city in Ontario by area and the fifth largest across Canada.
During the 20th century, the local economy was heavily dominated by a resource-based foundation centered on lumber and nickel mining. The historical trajectory of the region was largely shaped by two major mining corporations: Inco, which is now Vale Limited, and Falconbridge, now Glencore. By the 1970s, Inco alone employed more than 25% of the local population.
Economic challenges, including a major nine-month strike by Inco workers in 1978 that severely impacted the local economy, spurred municipal efforts toward diversification. The city subsequently expanded beyond its original resource-driven sector to emerge as the primary retail, economic, health, and educational hub for Northeastern Ontario. Today, the economy benefits from this broader institutional footprint while maintaining its connection to the surrounding Sudbury District, entirely surrounding it as a separate municipal entity.
