Special Announcement

During the December 1, 2021 project information update session, CBM announced that we will be excluding the southernmost 88 acres of land (outlined and shaded in orange in the figure below) from any future licence application, and for the entirety of the life of any potential quarry that may be approved. In addition to this exclusion, over the next while CBM will be exploring what we can do with these lands that will be directly beneficial to the community. We are very excited by the opportunity that this presents and look forward to working with the neighbours and community at large on what this might mean in the future. As mentioned during the update session, if you have any ideas that you would like us to consider please email David Hanratty, Director of Land & Resources, North America at: david.hanratty@vcimentos.com. We will provide on-going updates to the community as plans progress regarding these lands.

The Project – Proposed CBM Caledon Pit / Quarry


CBM has been exploring the opportunity and feasibility of developing a quarry in the vicinity of Charleston Sideroad and Main Street/Regional Road 136 in the Town of Caledon. The lands in this area are identified in the Town of Caledon Official Plan as a Caledon High Potential Mineral Aggregate Resource Area (CHPMARA). This reflects the fact that the bedrock in this area is considered a significant, high-quality aggregate resource in the province. CBM initiated multiple studies in February 2020 which have assisted in understanding the feasibility for extraction on these lands. As a result of these studies applications have been submitted to the province and the municipality for consideration.

We want to highlight that just because the aggregate resource is protected for a potential future quarry a thorough assessment and review of the applications is required. As part of the application process CBM carried out a very thorough evaluation from 2020 to 2023, which has included field work, background monitoring, scientific analysis, and the completion of technical reports that have been peer reviewed. Through this process CBM committed to communicating with the community on a regular basis, including before any application was made. As the applications have been submitted, they will be independently evaluated by professionals from several government agencies and by peer reviewers engaged by the municipality to ensure the safety of the community and compliance of the project with the appropriate regulatory requirements. Throughout the process, CBM is committed to continuing to keep the community informed on the status of the application.
