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.

Since 1935, the Mining Association of Canada (MAC) has been the national voice of the Canadian mining industry.
