About Waghorn, Stephens, Sipos and Poulton Law Professional Corporation

Waghorn, Stephens, Sipos and Poulton Law Professional Corporation is a general practice law firm in St. Marys, Ontario, that traces its roots to a legal practice founded in the town in the late 1800s. The firm has changed hands and names over the following century while staying rooted in the same community, and today its lawyers include John Sipos, Mark Poulton, and Michael Visser. It handles real estate, wills and estate planning, family law, civil litigation, corporate and commercial matters, and personal injury claims, and it also offers notary services and other general legal support.

Real estate makes up the largest part of the firm's work, at around 40 percent of the matters it handles in a typical year, followed by estate and wealth planning, then family law and civil litigation. Sipos earned a Bachelor of Laws from Osgoode Hall Law School in 1988 and was called to the Ontario bar in 1990, and earlier in that career served as the federal drug prosecutor for the County of Perth. Poulton joined the firm in 2007 as an articling student and has practiced law in St. Marys since. The firm describes itself as approachable rather than corporate, without the marble floors or high rise offices of a big city practice, and works from a ground floor office with on site parking on Wellington Street.

In the community

  • The firm supports local organizations including the Pyramid Centre, the St. Marys Hospital Foundation, the Rotary Club, Canada World Youth, and Children for Chernobyl, and volunteers with the local library.
  • John Sipos has volunteered on the town's Committee of Adjustment and its Local Architectural Conservation and Advisory Committee, volunteers with St. James Anglican Church, and has coached with the St. Marys Minor Soccer Association.
