About Mister Lawyer

Mister Lawyer is the working name of Piersanti Law Professional Corporation, a small real estate firm in Concord, a district in the city of Vaughan, Ontario. Founding lawyer Justin Piersanti grew up in Vaughan and earned a Bachelor of Fine Arts from Ryerson University in 2002, then spent several years working in the film and television industry before starting law school in 2007. Piersanti completed a Bachelor of Laws at the University of Leicester Law School in the United Kingdom in 2010 and a Master's of International Commercial Law, with Distinction, in 2012, and was called to the Ontario bar in 2014. In 2018, Piersanti opened an independent practice, Mister Lawyer and Piersanti Law.

The firm concentrates on residential and commercial real estate closings, along with business and corporate law, franchise law, trademarks, and wills and estates. Its transactions have ranged from a parking spot purchase worth about $20,000 to deals over $50 million, including work involving a real estate investment trust and appearances before the Local Planning Appeal Tribunal. Mister Lawyer caps its monthly closings so clients deal directly with the same lawyer rather than being passed between staff, and the firm doesn't charge for reviewing a standard OREA resale agreement or a new condominium purchase covered by a Tarion warranty.
