Northwestern Ontario is the next Mining Powerhouse!

As a regional exploration hub, mining is big business in Thunder Bay. Approximately 850 Thunder Bay residents work at mines, and 500 Thunder Bay mine service and supply companies support mining. In recent years, new discoveries and a strong metals market,  have driven interest in exploration and mining in Northwestern Ontario. 

Visit the Thunder Bay Mining Sector Supply & Services Directory for information on companies based in the Thunder Bay census metropolitan area (CMA) that supplies goods and services to the sector. The directory provides comprehensive contact information for the companies, interactive maps and is web linked (where available) to corporate websites.
