Free consultationSt. Marys goes by the "Stonetown", a fitting nickname for a town full of buildings made from locally quarried limestone. Heritage St. Marys, the town's municipal heritage committee, has led efforts to preserve those stone buildings.
The New Hamburg office is on Peel Street in a community at the far western edge of the Region of Waterloo, close to the Perth County line. The Nith River runs through its downtown, which is a designated Heritage Conservation District. A 50-foot wooden waterwheel built there in 1990 came down on March 15, 2023, and a metal recreation took its place.
The third office is on St. Catherine Street in St. Thomas, which received its city charter on March 4, 1881, and serves as the seat of Elgin County while staying independent of it.
