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:

  • 28,000 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.

Ontario’s investment targets - progress to date

Our minerals sector continues to grow. In 2020, there were $2.1 billion in capital investments into Ontario’s mining sector, compared to the baseline low of $1.877 billion over the last five years. This shows progress toward the 2023 target of $2.5 billion.

Investments in mineral exploration, development, and mining in Ontario increased in 2021. Ontario’s share of the Canadian market share of exploration expenditures increased to 27.2%. This is above the baseline low of 24.2% over the last five years and the 2024 target value of 26.5%.
