About McKenzie Lake Lawyers LLP

McKenzie Lake Lawyers LLP is a full-service firm that was founded in 1998 in London, Ontario, when two practices whose roots reach back to the 1930s merged. Today it's home to more than 60 lawyers across three Ontario offices, in London, Guelph, and Strathroy. Community giving has been part of the firm from its early days and continues across the practice today.

The Guelph office opened in July 2022, when four partners and their legal teams joined from a national firm. From Guelph the firm handles agri-business, business and real estate law, family law, personal injury and disability claims, wills and estates, and succession planning. The wider practice runs from one of the largest family law departments in Southwestern Ontario to litigation covering personal injury, contract disputes, tax matters, and the defence of professional negligence claims. Canadian Lawyer has named the firm a Top 10 Ontario Regional Law Firm four times, and Best Lawyers placed it on the inaugural Best Law Firms in Canada list for 2025.

The neighbourhood

The Guelph office sits on Stone Road West in the city's south end, a commercial corridor that runs along the southern edge of the University of Guelph and continues west toward Stone Road Mall. Guelph and the surrounding townships of Wellington County are farm country, and the University of Guelph itself grew out of the Ontario Agricultural College, which opened in 1874. That makes it a natural base for a practice that covers agri-business and farm succession alongside the family law, real estate, and estates work the firm does for the wider community.
