About Koskie Minsky LLP

Koskie Minsky LLP is a Toronto law firm that began as a small union-side labour practice. Today it works across four main areas: labour law, class actions, pension and benefits, and civil litigation, from an office at 20 Queen Street West in downtown Toronto. On the labour side, the firm represents unions, workers, and professional groups rather than employers, handling collective bargaining, grievance arbitration, human rights complaints, and occupational health and safety matters. Its class action practice covers a wide range of subject areas, including residential schools, Crown liability, environmental claims, securities misrepresentation, employment law, and consumer protection.

The pension and benefits group advises and represents pension funds, plan boards of trustees, and other administrative bodies, including multi-employer plans, and handles pension litigation and regulatory proceedings. In 2013, Koskie Minsky formed a strategic affiliation with Glavin Gordon Clements of Vancouver, creating Koskie Glavin Gordon and extending union-side and employee-side legal services to British Columbia. One detail fits the firm's labour-side focus: its own articling positions are unionized, under C.U.P.E. Local 1281.
