Health, Information Technology, Privacy

A partner with the Toronto firm DDO Health Law in Toronto, Mary Jane Dykeman divides her practice between health law and data law matters. She advises clients on a broad range of health law matters including risk management and strategic advice, mental health, consent, capacity and substitute decision-making. A significant area of her practice is devoted to privacy, cyber security, and artificial intelligence (AI).

Ms. Dykeman was called to the Ontario Bar in 1998 after receiving her law degree from Osgoode Hall Law School in 1996, and an Honours Bachelor of Arts in Bioethics from Mount Allison University in 1989. She has acted as in-house legal counsel to two Toronto teaching hospitals.

She founded the Mental Health Law course in Osgoode Professional Development’s Health Law LL.M. program, which she continues to teach with Michele Warner; as well as Osgoode’s Mental Health Certificate Program (now co-directed by Kristin Taylor and Michele Warner, Centre for Addiction and Mental Health.)

With the Advocacy Centre for the Elderly, Ms. Dykeman has co-authored two Law Commission of Ontario papers on health-care consent and advance care planning, including end-of-life practice tools. Her understanding of health system co-ordination for seniors, advance care planning, long-term care and end of life enables her to provide key compliance and wise counsel. Ms. Dykeman is the primary author of two toolkits developed with AdvantAge Ontario, a member association serving the long-term care sector, on medical assistance in dying and cannabis legalization, respectively. She also works extensively on challenging patient and family issues, and more recently on tools for family caregivers with The Change Foundation.

Ms. Dykeman provides practical privacy advice in the public and private sectors, and is a sought-after speaker. She responds to privacy breaches, advises on the creation of complex shared information systems, and trains extensively on legislative requirements and emerging trends.

Frequently assisting clients on issues that create significant clinical or enterprise risk management, Ms. Dykeman is often behind the scenes, providing strategic counsel and supporting senior teams to address the most difficult issues. This includes disruptive situations involving staff, patients/residents/clients and family members; as well as on shaping public policy in emerging areas such as AI.

Ms. Dykeman is vice-chair of the Alzheimer Society of Toronto board, and deputy chair of the Research Ethics Board of Canadian Blood Services. With Dr. Julia Spence, she has a platform for family caregivers of seniors, at
