Marion Sandilands
Available in: English Français

Marion’s practice focuses on public, constitutional, and administrative law, informed by her clerkships at the Supreme Court of Canada and Federal Court.

Marion’s interest in public law stems from her background, and first career, in international development and public policy. Today she advises and represents a number of clients, notably institutional clients in the educational sector, as well as Aboriginal clients, on matters of administrative law, human rights, general legal obligations, statutory interpretation, minority rights, and language rights.

Marion joined Power law in 2016 after clerking for Justice Andromache Karakatsanis of the Supreme Court of Canada. Prior to that, she clerked at the Federal Court of Canada with Justices Marie-Josée Bédard and Yves de Montigny.

She practices in English and French.

  • Prior to joining the legal profession, Marion studied and worked for several years in the field of international development. Her Master’s work at Carleton University’s Norman Paterson School of International Affairs focused on how the modernisation of international value chains affects primary producers such as coffee farmers and horticulturalists, and how public policy or programs might intervene to improve the prospects of these primary producers. She co-authored a published paper on an international coffee retailer’s value chain practices and completed a major research paper on the impact of supermarkets on small-scale horticulture farmers in Kenya.

  • Marion has held positions in program management with a non-governmental organisation specialised in rural development (2007-2009), and with an international research-funding organisation in the area of sustainable economic growth (2009-2011). Her work with these organisations brought her to Kenya, Vietnam, Senegal, and Mexico, among other places.

  • While at McGill University, Marion bridged her interest in international development with her legal pursuits. She worked with the McGill Law Journal, the Centre for Human Rights and Legal Pluralism, and the Labour Law and Development Research Laboratory. Upon graduating on the Dean’s Honour List, she was awarded the Alumnae Graduation Award.
