CBM (Canada Building Materials) Aggregates, an operating division of St Marys Cement, is proposing to construct and operate the Bowmanville Underground Expansion Project (the Project), to be adjoining CBM Aggregates’ existing licensed quarry area situated on the shore of Lake Ontario within the Municipality of Clarington.
We strive to have a long-term, positive impact on people and our planet. Before commencing with the proposed project, we are conducting an in-depth assessment to understand the potential environmental impact of the project and to ensure a safe operating environment for our employees and the surrounding community.
The ProjectThe Project will extend beyond the existing site beneath the lake to extract limestone from an underground mine to be located beneath the bed of Lake Ontario. CBM Aggregates is looking at alternative sources of limestone, including the underground sources associated with the Project, due to the increasing scarcity of high quality limestone occurring within certain parts of Ontario. We are working closely with the Ministry of Northern Development and Mines (MNDM Class EA) to plan and conduct the Environmental Evaluation process. As part of project planning, CBM Aggregates has been engaging with communities and is now formally entering the Class EA process.
