She continues to represent clients who have been discriminated against in human rights cases.

    In 2023, Jen was counsel in two successful constitutional challenges to the eviction of homeless encampments in Waterloo and Kingston.

    A significant portion of Jen’s practice is dedicated to representing victims of violence, sexual assault and child abuse. This involves advocacy in criminal proceedings and pursuing civil claims against the perpetrators and the institutions that facilitated the abuse.  She is a cofounder of Legal Advocates Against Sexual Violence (LASV).

    Jen is passionate about elder law and assists clients in navigating disputes about how to make personal care and financial decisions for family members under the Substitute Decisions Act, 1992. She frequently represents allegedly incapable persons and has been appointed amicus curiae in various contexts.

    This past year, Jen represented the family of the late Attila Csanyi in a Coroner’s Inquest.  Attila was a young Romani man from Hamilton, Ontario who died of a drug overdose after being unlawfully evicted from a Residential Care Facility (RCF) at the beginning of the COVID-10 pandemic.
