Michael Wilson is a partner in the Litigation Group at Goodmans. He acts for public and private companies, directors and officers, and government agencies in litigation and arbitration, focusing on corporate, commercial, administrative law and regulatory matters.

Michael has appeared before the Ontario Superior Court of Justice, the Federal Court of Canada, and international and domestic arbitration panels.

Until recently, Michael served as the chief of staff to the Attorney General of Ontario. Providing strategic counsel to two successive Attorneys General, Michael led the development and implementation of substantial legislative reform, including the modernization of legislation related to Ontario’s crown liability, class actions, civil forfeiture, police oversight, construction and legal aid. He routinely advised on policy development related to regulated professions and industries, including those regulated by the Alcohol and Gaming Commission of Ontario (alcohol, gaming, and cannabis). In particular, Michael was instrumental in the design of Ontario’s Cannabis Licence Act and Cannabis Control Act that provide the framework for Ontario’s open-market, privately-operated cannabis retail market.

In addition to his litigation practice, Michael continues to build on his experience advising decision-makers in the federal and provincial government by assisting clients with crisis mandates and strategic policy and regulatory advice.  He advises corporate clients and industry associations in developing legislative and regulatory proposals that respond to complex and urgent policy challenges.
