Working with the community has always been a priority of St Marys Cement, providing dependable economic opportunity to the residents of the town, while contributing to community building efforts and interests. The Community Liaison Community (CLC) works to ensure that residents are informed of the work that St Marys Cement is doing, and that they have a forum to ask questions or raise concerns. It was formed to build on the relationship between the community members of St. Marys and the St Marys Cement Plant.
St Marys Cement has contributed resources, land, materials and more to strengthen the community. SMC was instrumental in the opening of St. Mary Memorial Hospital in 1950, and since then, has donated land for the Canadian Baseball Hall of Fame. This donation provided resources for the growth of the swimming quarry, the Pyramid Centre, and the redevelopment of Cadzow Park. Moreover, this continued support for community initiatives like hockey teams and the local hospice.
