Christie’s practice focuses on land use planning law, but also encompasses all aspects of municipal and environmental law, including tax assessment appeals and expropriations. Her experience includes representing public and private sector clients before the Ontario Land Tribunal (formerly, the Local Planning Appeal Tribunal, formerly the Ontario Municipal Board), and she has also appeared before the courts. For her work, Christie is consistently recognized by Best Lawyers as “One to Watch” in Municipal law and Real Estate law.

In addition to her law practice, Christie serves as Past-Chair on the Ontario Bar Association’s Municipal Law Executive, having previously served on the executive in the roles of Chair, Vice-Chair, newsletter editor, and at-large member since 2016. She has also served on the Canadian Bar Association’s Municipal Law Executive. She also serves as Co-Vice Chair of the board of the United World Colleges Canadian National Committee and gives back to her alma maters through the Cornell Alumni Admissions Ambassador Network, Cornell University new student welcome events, and volunteering with the Osgoode Women’s Network as a mentor. Christie serves on the steering committee for the Cambridge Forum on Land Use Planning: The Emerging Leaders, and is an active member of BILD and ULI (former chair of the ULI Toronto Mentorship Program and steering committee member of WLI). She also has recently completed a term on Cassels’ Women’s Advancement, Voices and Equity Committee.

Prior to joining Cassels, Christie worked with a boutique urban planning law firm in Toronto practising in the area of development/land use planning, property tax assessment, expropriation and municipal law. Prior to her call to the bar, Christie summered and articled with a large international full-service firm in Toronto. Christie obtained a B.A. in Economics from Cornell University in 2010, a J.D. from Osgoode Hall Law School in 2013, and a Women in Leadership Certificate from Cornell University’s SC Johnson College of Business in 2019.
