The Constitutional Law Branch (CLB) provides advice to the Ontario government regarding constitutional issues pertaining to programs, policies, and legislation as well as constitution reform. While our practice is mostly civil litigation, we often handle significant constitutional issues in provincial prosecutions.  We also act as the government’s counsel during constitutional challenges at all levels of court.  

Our cases often raise issues of national public importance and therefore tend to garner significant attention. Our practice is fascinating, intellectually challenging and complex. The work requires a flexible, sensitive and creative approach to legal and public policy issues, in addition to a sound knowledge of the law. The concentration of expertise in constitutional litigation and law in the Branch is difficult to find elsewhere in Canada.
