The Law Society of Ontario (LSO) is the statutory self-regulatory body responsible for governing the legal profession in the province of Ontario, Canada. Established in 1797 as the Law Society of Upper Canada and renamed in 2018 to reflect reconciliation and recognition of Ontario's Indigenous heritage, the LSO oversees professional standards, ethical conduct, and public protection. It licenses and regulates over 60,000 lawyers and 10,000 paralegals, sets rules for professional practice, handles complaints, conducts investigations into misconduct, and imposes disciplinary measures when necessary. Operating independently under legislative authority with headquarters at Osgoode Hall in Toronto, the LSO manages key functions including approval of law schools, continuing legal education requirements, and administration of the lawyer licensing process. It engages in public education, policy development, initiatives to promote diversity and equity within the profession, and plays a pivotal role in shaping legal policy through consultations with government and stakeholder groups. The LSO's governance structure includes an elected council comprising lawyers, paralegals, and public representatives, ensuring balanced oversight. It has faced controversies over issues like mandatory fees, diversity initiatives, and responses to professional misconduct allegations, but remains a cornerstone of Ontario's legal system, influencing networks of legal influence, professional accountability, and public trust in the justice system.
