About Wynne, Pringle, Jeske & Keesmaat LLP

Wynne, Pringle, Jeske & Keesmaat LLP practices from Ancaster's historic downtown section, in a part of Hamilton that was its own town until Ontario's 2001 municipal amalgamation. The firm's roots go back to the 1970s, and it has worked from the same Ancaster address since 1978. Robert G. Wynne, called to the Ontario bar in 1974, was a partner at McKeon and Wynne and then at Wilkins, Wynne, Horodyski and McCluskey before founding Wynne & Dingwall in 1998, the partnership that grew into today's firm. The name changed again in 2026, when Andrew L. Keesmaat made partner, a few years after longtime lawyer Ron Kovacs retired at the end of 2022.

Seven lawyers and a staff of 14 handle business and corporate law, real estate and real estate development, wills and estates, and mortgage enforcement, acting for financial institutions and private lenders that need power of sale or foreclosure remedies. The firm has practiced business law for more than 35 years and can quote block fee rates on development files so a project's legal costs stay predictable. Its estate, capacity, and elder law litigation practice draws on a partner's Osgoode Certificate in Elder Law from Osgoode Hall Law School. The firm's clients come from Ancaster, greater Hamilton, and beyond.
