Place and region
St. Marys is a small town in Perth County, south-western Ontario, on the Thames River, with a heritage downtown and the Canadian Baseball Hall of Fame. It lies between Stratford and London, with Woodstock and Ingersoll to the south and South Huron and Huron East to the north and west. Buyers include commuters, retirees and downsizers.
What makes the town attractive
St. Marys gives buyers a walkable centre, a limestone quarry converted into a swimming spot and a quieter pace than London or Kitchener-Waterloo. Houses with three bedrooms dominate, so first-time buyers and young families make up much of local demand. The median size of 102 m² is compact, which is partly why the median price per m² (€3,306) is higher than in larger-home towns. Heritage homes need roof, wiring and foundation checks, and a pre-purchase inspection is standard in Ontario.
Foreign buyers
Federal restrictions apply until 1 January 2027 and Ontario charges a 25% Non-Resident Speculation Tax. Older stone houses need careful inspection. Ontario also levies land transfer tax on completion.

Buying property in St. Marys: FAQ
Is St. Marys close to London, Ontario?
They are in the same part of south-western Ontario and about half an hour apart by road. See the London page for comparison. Stratford offers theatre and a bigger shopping base, while London has a hospital and a university.
Why is it called Stonetown?
Many downtown buildings are limestone. Heritage properties may come with restrictions, so ask about designation. Check the listing for any heritage designation before planning renovations.
Do I pay land transfer tax?
Yes, Ontario charges a progressive land transfer tax on completion, separate from the NRST. Land transfer tax is calculated on the price in tiers, so ask your lawyer for the exact figure.
Are there condos?
12 of 77 listings are apartments, usually in smaller buildings. Check condo or strata-style fees for each building, as they affect monthly costs.
