About GC Boyle Law Firm

GC Boyle Law Firm is a general practice rooted in St. Marys, the Perth County town southwest of Stratford. Its head office sits at 172 Queen Street East, in the downtown core, and it runs two satellite offices, one in New Hamburg and one in St. Thomas. The firm handles a broad mix of everyday legal work: real estate and mortgages, wills and estates, family law, business law, employment matters, litigation, personal injury, and landlord and tenant issues, plus notarizations, commissioning, and legal letters. It doesn't take criminal cases. The people who run it live and work in St. Marys, and the firm describes itself as a community practice that listens first.

Founding director Gwendolen Boyle studied both psychology and law, holding an honours psychology degree from Western University and a law degree from the University of Ottawa, and focuses on estates, family law, and advisory work. The rest of the team includes an associate lawyer working in civil litigation, family, and employment matters, a real estate manager with more than 25 years in real estate law, a paralegal handling Small Claims Court and landlord and tenant disputes, and a law clerk. One detail is unusual for a law office: it keeps support animals, Hazel, Stevie, and Bruno, on hand to help clients feel at ease during stressful visits.

The neighbourhood

The head office stands at 172 Queen Street East, on the main street of a town that built itself out of local stone. St. Marys is nicknamed the Stonetown for its 19th-century limestone churches, commercial blocks, and homes, and much of the downtown falls inside a Heritage Conservation District of century-old buildings. The town grew up where Trout Creek meets the Thames River, at the ledges where the water once powered the first mills. For a firm that does a lot of local real estate, wills, and family work, a Queen Street address keeps it in the middle of the community it serves.
