The Canadian Legal Information Institute or CanLII is a free legal information research database covering case law from all Canadian courts, including the Supreme Court of Canada, federal courts, and the courts in all Canada’s provinces and territories, plus federal legislation and consolidated statutes and regulations of every jurisdiction in Canada.

A companion website, CanLII Connects, hosts a database of case commentary and case summaries by the legal community, with links to the case law on CanLII.

CanLII was founded and is paid for by the lawyers and notaries who are members of Canada’s provincial and territorial law societies, which comprise the Federation of Law Societies of Canada. Its technology and editorial services are provided by Lexum. CanLII is founding member of the Free Access to Law Movement and a signatory to the Montreal Declaration on Free Access to Law.
