Litigation: Administrative & Public Law | Canada

Ontario

This section ranks those firms and individuals which advise on civil litigation on behalf of businesses, high net worth individuals and other non-public sector entities. The primary focus of this section is corporate litigation and litigation arising out of commercial arrangements, including shareholder disputes, post-M&A disputes and contractual disputes. Less weight is given to civil litigation types which are covered elsewhere in the Canada Guide, for example banking litigation, professional negligence, civil fraud, insurance or restructuring/insolvency. Disputes involving public sector bodies (judicial reviews, procurement challenges, etc.) will not be covered in this section. Inquests, public inquiries, tribunals, regulatory investigations and related enforcement actions will not be covered in this section. This chapter exclusively covers courtroom litigation, rather than alternative dispute resolution methods like mediation and arbitration.
