What Cavalluzzo does
Cavalluzzo LLP is a Toronto-based law firm founded in 1983 by Paul Cavalluzzo, Jim Hayes, and Elizabeth Shilton, specializing in union-side labour and employment law with a stated commitment to social justice and equality. The firm operates from a single renovated warehouse office at 474 Bathurst Street in downtown Toronto and serves unions and their members across healthcare, education, construction, postal, public service, and telecommunications sectors; individual employees facing wrongful dismissal, workplace discrimination, and human rights matters; and regulated professionals navigating discipline and licensure issues. Its core practice areas include union-side labour law (collective bargaining, certification, unfair labour practices, strikes and lockouts, labour arbitration), employment law for employees, class actions, pensions and benefits, human rights law, Charter and constitutional litigation, professional regulation, Indigenous rights, and public interest advocacy.
The firm's distinguishing capability is its concentration on union-side advocacy and constitutional litigation, including a leading track record in Supreme Court of Canada section 2(d) Charter freedom of association cases such as Saskatchewan Federation of Labour v. Saskatchewan and the OECTA constitutional victory. Notable outcomes include a pay equity win delivering a $5.31/hour increase plus benefits for Canada Post rural/suburban mail carriers. The firm has no proprietary technology platform, no AI/ML capabilities, no API or SDK offerings, and no mobile applications; service delivery is entirely human-driven through direct client consultation, retainer engagements, and representation before labour boards, human rights tribunals, and courts. Marketing relies on content marketing (blog, news, legal analysis publications), professional conference participation (Lancaster House, Infonex, OECTA grievance seminars, ETFO, Vertra Forums), and thought leadership on legislative developments (Bill C-58, Bill 148, Bill 195).
Cavalluzzo is structured as a private limited liability partnership under Ontario law with no external investors, parent company, or PE/VC ownership. Revenue is generated entirely through professional services billings on client-specific matters, with no public pricing or standardized fee tiers disclosed. The firm has expanded its partnership internally through promotions (Tyler Boggs in 2025; Niiti Simmonds and Michael Mandarino; Aminah Hanif and Lauren Sheffield) and has earned consecutive recognition in Best Lawyers (2024-2026), Chambers Canada Guide (2026), Best Law Firms (2025), and Globe and Mail Canada's Best Law Firms (2025). Total headcount is reported as 51-100 employees, including approximately 30+ lawyers plus articling and summer students.
