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. Relevant work for Litigation: Administrative & Public Law will primarily focus on public sector disputes. Judicial reviews, public inquiries, constitutional challenges, parliamentary investigations and other public body disputes are considered, as are broader disputes with public sector interest, including some municipal, privacy and extradition matters. Relevant work for the Litigation: Securities section includes securities class actions, shareholder disputes, proceedings before provincial regulatory agencies and investigations, brokerage disputes and contested takeovers, as well as misrepresentation, oppression, breach of trust and insider trading cases. This chapter exclusively covers courtroom litigation, rather than alternative dispute resolution methods like mediation and arbitration.
