The Ontario advantage

Ontario’s rich mineral resources make us a global leader in mining and exploration. Our mining industry is a major economic engine that supports local economies in every corner of the province. Mineral production in Ontario supports:

  • 31,000 direct jobs
  • 47,000 indirect jobs associated with mineral processing and mining supply and services

We understand the changing perspective of the investment community, including meeting our environmental, sustainable and governance (ESG) objectives. We are committed to creating a safe and profitable investment climate that helps investors meet their ESG goals.
