Virtual appointmentsMason Bennett Johncox is a law firm based in Brooklin, Ontario, with a second office in Port Perry, serving Durham Region and south-central Ontario. Robin Mason and Patrick Bennett founded the firm in Durham Region in 1994. Ian Johncox, who was called to the Ontario Bar in 1996, joined soon after and has practiced in the region since then. The firm's lawyers work in business and corporate law, employment law, real estate law, civil litigation, wills and estate administration, and mediation, and the firm also offers notary and commissioner services.
A few lawyers on the team bring experience from outside Durham Region. Jocelyne Boissonneault practiced intellectual property litigation in Silicon Valley from 2001 to 2004 before returning to focus on criminal and mental health law, and belongs to both the Law Society of Ontario and the California State Bar. Robin Mason, now retired from the firm, is a Registered Canadian Trademark Agent. Ian Johncox wrote a business law column for the Durham Business Times from 1999 to 2009 and a column called Legal Briefs for Kawartha Lakes This Week from 2000 to 2007. The Brooklin office is in a historic building on Baldwin Street North, and the Port Perry office operates out of the Allison House, built in the 1880s.
