Jay Naster


Jay Naster is a partner in our criminal and regulatory law group.

Jay's practice focuses on white-collar criminal and regulatory litigation and investigations, and the frequent intersection with civil liability.

Following his call to the bar in 1986, Jay spent eleven years as a Crown counsel with the Crown Law Office (Criminal) where he specialized in complex white-collar criminal prosecutions, including corporate/commercial, securities and tax-related matters. In 1997 Jay became the senior litigation counsel at the Ontario Securities Commission, where he conducted complex quasi-criminal prosecutions and regulatory hearings pursuant to the Securities Act.

Since entering private practice in 2005 with the firm Rosen Naster LLP, Jay has represented individuals and corporations who are under investigation or charged with white-collar criminal and quasi-criminal offences, as well as alleged regulatory and professional disciplinary violations. This includes successfully defending clients accused of fraud, theft, breach of trust, secret commissions, foreign corrupt practices, insider trading, market manipulation, price fixing and tax evasion (income and HST/GST). Jay has also successfully defended clients charged with offences under occupational health and safety, licensing, and provincial taxing statutes. Jay also regularly defends individuals and corporations alleged to have breached regulatory and professional disciplinary codes of conduct applicable to investment advisors, portfolio managers, lawyers, and corporate officers and directors.

Jay's experience and expertise also extends to providing advice on the conduct of complex investigations, including due diligence inquiries and internal investigations, working closely, as may be appropriate, with forensic accountants, police and regulatory officials, as well as with adverse parties, in an effort to achieve effective and efficient resolutions of potential disputes, including resolutions that do not require recourse to the Courts.

With his proven record of experience and expertise, Jay is uniquely positioned to serve the special needs of senior officers, directors and advisors of public and private corporations, investment dealers and other market participants whose conduct has been called into question and is the subject of investigation and/or proceedings before the courts or regulatory and disciplinary tribunals, either as defendants, respondents or witnesses.

Jay is a frequent speaker at continuing legal education conferences in his areas of expertise. He is a past lecturer at the University of Toronto, where he co-taught a course on white collar crime. He periodically lectures to law school and business school classes, and is currently an instructor in the trial advocacy program at the University of Toronto.

Jay received his LL.B. cum laude from the University of Ottawa. He was called to the Bar of Ontario in 1986. He is a member of a number of professional associations including the Advocates Society and the Canadian Bar Association.
