Christie is a member of Miller Thomson's Commercial Litigation Group, and focuses on environmental, Aboriginal, administrative, and other litigation matters.

Christie joined Miller Thomson as a student in 2019 and concluded her articles in 2021. She completed the joint JD/Masters in Environmental Studies program at Osgoode Hall Law School and York University, with the latter focusing on Canadian climate accountability. During her education, Christie also worked with Human Rights Watch in New York City and Toronto to research the impact of climate change on food security in Indigenous communities in Canada, and with West Coast Environmental Law as a summer student and legal researcher.

Christie appeared before the Standing Committee on Environment and Sustainable Development as a witness regarding Bill C-12 (The Canadian Net-Zero Emissions Accountability Act). In this role, Christie authored and submitted a brief which nearly 200 youth and youth-led organizations signed onto, as well as co-authored a brief submitted by Lawyers for Climate Justice. In 2020, Christie co-authored a successful Formal Request to Minister Wilkinson for a Regional Assessment for the Ring of Fire region in Ontario.

Christie also drafted an open letter to Prime Minister Justin Trudeau and Federal Environment Minister Jonathan Wilkinson in 2019 calling for Canada to adopt and legislate stronger emissions reduction targets, which was signed by nearly 500 law students and law faculty members from across Canada.

Prior to law school, Christie served as the Executive Director of a non-profit organization devoted to children’s education and healthcare in East Africa. She concurrently founded Human Rights Hub Winnipeg, an initiative that raises awareness about local human rights issues and promotes events and opportunities in Winnipeg’s vibrant human rights sector. Christie continued to manage and grow this initiative through law school, and remains a Director of the organization today.

Christie also serves as a member of Lawyers for Climate Justice and a Policy Advisor for the Fossil Fuel Non-Proliferation Treaty Global Steering Committee.
