Ontario Mining Association

The Ontario Mining Association (OMA) was established in 1920 to represent the mining industry of the province and is one of the longest serving trade organizations in Canada. We have a long history of working constructively with governments and communities of interest to build consensus on issues that matter to our industry and to the people of this province.

Our success in advocating for industry advancement is based on our ability to harness the collective strength of our highly engaged members. We are proud to serve as a focal point for discussions on the issues and opportunities facing our community and to offer our members a unified voice on matters of public policy and opinion. Our goal is to overcome challenges that impede the competitiveness of responsible operations and to foster an environment that bolsters mining's potential to be the cornerstone of Ontario's new, innovation-oriented green economy.
