About Ambrosini Law Professional Corporation

Ambrosini Law Professional Corporation is a small Toronto firm built around a single focus: mental health law. It operates from University Centre at 393 University Avenue in the city's downtown core, and launched its current website in October 2020.

The practice centres on Daniel Lamberto Ambrosini, called to the Ontario bar in 2010. Ambrosini holds a PhD and an MSc in psychiatry along with an LLB/BCL in common and civil law, all from McGill University, and completed a post-doctoral fellowship at Harvard Law School in 2013. Ambrosini serves as a lawyer member of Ontario's Consent and Capacity Board and holds a part-time appointment as Assistant Professor in the Department of Psychiatry and Behavioural Neurosciences at McMaster University. That combination of legal training and psychiatric research shapes the firm's work: capacity and consent hearings, appearances before the Ontario Review Board in forensic psychiatry matters, and mediation of estate and substitute decision making disputes where mental health issues intersect with the law.

Associate lawyer Aniqa Rashid joined the firm with a background in forensic psychology and mental health research and handles criminal defence, medical malpractice, elder law, wills and estates, and personal injury matters, extending the firm's reach while keeping the same focus on capacity and consent issues.

The neighbourhood

The firm's office sits in University Centre, a Class B office tower at 393 University Avenue built in 1974, in the middle of Toronto's downtown institutional corridor near provincial government offices.

That location fits a practice that spends most of its time in front of provincial boards and tribunals rather than a traditional courtroom: hearings on capacity and consent, and appearances before the Ontario Review Board in forensic psychiatry matters, are the firm's regular work.
