Your Guide to the Stone Town


St. Marys is a town in southwestern Ontario, Canada. It is located at the junction of Thames River and Trout Creek southwest of Stratford, and is surrounded by the Township of Perth South in Perth County, Ontario. St. Marys operates under its own municipal government that is independent from the County's government. Nonetheless, the three entities "enjoy a large degree of collaboration and work together to grow the region as a leading location for industry and people". Census data published for Perth County by Statistics Canada includes St. Marys and most Perth County publications also do, at least in some sections of the document.

The town is also known by its nickname, "The Stone Town", due to the abundance of limestone in the surrounding area, giving rise to a large number of limestone buildings and homes throughout the town. St. Marys Cement, a large cement producer founded in the town, capitalized on this close feed stock, and grew to be a major producer of cement in the province of Ontario.

St. Marys is home to the Canadian Baseball Hall of Fame. It is the burial place of Arthur Meighen, Canada's 9th Prime Minister. Timothy Eaton, who went on to become one of Canada's most famous retailers, opened his first businesses in Canada in nearby Kirkton, Ontario and later St. Marys.

    This lovely home was built in 1879 and designed by architect Silas Weekes. 220 Elgin St E is a Georgian-style heritage home with 10' ceilings and carries the kind of craftsmanship that's become rare, and it's the sort of house made to hold a family for many years. The baseboards set the tone the moment you step inside, a full foot tall and running through the main level with a quiet sense of grace. The dining room is generous enough for the whole family, lit by two solid brass fixtures, with a bar tucked between it and the kitchen. Hardwood flows through both the dining and living rooms, and the living room welcomes you with a gas fireplace for the colder months. In the kitchen, a wood stove brings a gentle warmth to winter mornings. Just beyond, you'll find a pantry and an office, and the office opens onto the back deck, where a few steps lead down to the grass, the perennial beds, and a small pond. The main level also offers a theatre room, complete with real theatre chairs, lovely as it is for movie nights and just as easily reimagined as a main floor bedroom. A powder room finishes the level for guests. Upstairs, pine floors carry you through three well-sized bedrooms and two three-piece baths, with a washer and dryer placed on the same level. The detached garage is currently given over to woodworking, with a working blacksmith forge at the back, ready for you to keep, use, or reimagine. The home rests easily on its street, among the heritage houses that surround it, and within walking distance of downtown, the schools, the rec centre, and the senior centre. As for St. Marys, they call it Stonetown for good reason. Its limestone buildings rose through the 1800s when the quarries were thriving, and much of that architecture still stands beautifully today, including the Opera House, another Silas Weekes design. Add a charming main street, the Grand Trunk Trail, and the outdoor quarry in summer, and you have a town people settle into and rarely leave. More details
