Community Involvement

Walker Aggregates supports a variety of community initiatives across Ontario. In the past, our support has come in the form of stone donations, employee volunteering, fundraising and sponsorships. We offer tours of our sites to local schools to enhance their classroom learning experiences. We strive to build and participate in the communities in which we live and operate.

To learn more about how we, along with the other divisions of Walker Industries, serve our communities, check out ourĀ 2018 Sustainability Report.
