About Horner Pietersma Stewart

Horner Pietersma Stewart is a general practice law firm in Morrisburg, Ontario, with roots that go back more than 60 years to a predecessor practice called McInnis and MacEwen. Eldon Horner joined that firm in 1996, and when Eric Pietersma joined in 2003 it took the name Horner & Pietersma. Kristen Godwin-Stewart made partner in July 2025, and the firm adopted its current name, Horner Pietersma Stewart, to mark the change.

The firm now has 5 lawyers and 11 support staff working from its Morrisburg office, several with decades of tenure there. Its practice covers real estate, wills and estates, business and corporate law, family law, civil litigation, and municipal law, along with agricultural law, a specialty that reflects the farming communities of South Dundas and the surrounding Eastern Ontario counties it serves. The firm describes many of its clients as staying with it across generations, a detail consistent with a practice that has worked from the same Main Street address under a series of names for six decades.
