Cornerstone Celebrates Ontario’s First Certified Aggregate Site

On Monday evening Cornerstone gathered together with elected officials, environmental CSC-PREVIEW-3champions, community advocates, aggregate operators, First Nations members and aggregate operators to celebrate our very first certified responsible aggregate site.

The certificate, which was presented to CRH Canada Group Inc for Phases 1, 2 and 3 of its Acton Quarry, means that stone, sand and gravel from the quarry will now carry the Cornerstone CSC label. And, for the first time ever, buyers will be able to purchase aggregate materials knowing they come from an operation that protects the environment, engages openly with the community and operates following industry best practices. For aggregate operators, CSC’s certification promises a less contentious licensing process and a new way to earn community support.

Joining us for the celebration were Premier Kathleen Wynne, Bill Maura, Minister of Natural Resources and Forestry, Ontario’s new Environmental Commissioner Dianne Saxe, Chief Ava Hill of Six Nations and mayors and councillors from Halton Hills, Puslinch, Caledon and Bracebridge.



Financial support for Cornerstone’s work has come in part from progressive aggregate operators but significant contributions from Metcalf Foundation, Ontario Trillium Foundation and The Schad Foundation have been key to the organization’s success. During a short ceremony former CSC Chair and Executive Director of The Schad Foundation, Peter Kendall presented Baudouin Nizet, President & CEO of CRH Canada Group with CSC’s first certificate of conformance.

For CRH Canada the certificate is recognition for a commitment to a higher standard of practice. “CRH Canada and Dufferin Aggregates are extremely proud that our Acton Quarry has been officially recognized as the world’s first certified responsible aggregate site, and hope that this achievement will be a catalyst for the industry.  This certification is a testament to our commitment to address the demand for aggregates that consider community and environmental needs. Now any purchaser of aggregates, be it the public or the private sector, will have the confidence in knowing that they are buying responsibly sourced building materials”, said Baudouin Nizet, President & CEO, CRH Canada Group Inc.
