About Shnier Mackenzie Law

Shnier Mackenzie Law & Policy Consulting, Professional Corporation is a small law firm at 1905 Avenue Road in Toronto. It's led by founder Dr. Adrienne Shnier and partner Jonathan Mackenzie, whose surnames make up the firm's name, alongside Daniel Rizzi as counsel and Vanessa Caco as a licensed paralegal.

Dr. Shnier holds a J.D. from Osgoode Hall Law School and a Ph.D. in Health Policy & Equity from York University, and was called to the Ontario bar in 2020. That academic background shapes the firm's health law and public policy consulting practice, which advises physicians, dentists, physiotherapists, chiropractors, and other regulated health professionals and their associations on compliance, governance, and contracts. Jonathan Mackenzie, called to the bar in 2011, spent years in insurance defence and personal injury litigation before moving in-house as corporate counsel at a national real estate franchisor, and now handles the firm's business, franchise, and employment law files. The firm also takes on family law matters, including divorce mediation, and both Dr. Shnier and Jonathan Mackenzie are commissioned as notaries public in Ontario.
