Willms & Shier Environmental Lawyers

What Willms & Shier Environmental Lawyers does

Willms & Shier Environmental Lawyers LLP is a privately held Canadian boutique law firm founded circa 1974, organized as a limited liability partnership and headquartered in Toronto. The firm specializes in environmental, Indigenous, and energy law, operating across five core practice areas: environmental (including air law, climate change litigation, contaminated land, waste law, water law, ESG, environmental compliance and due diligence), Indigenous legal issues, energy law, Northern law, and litigation. It maintains offices in Toronto (headquarters), Ottawa, Calgary, and Yellowknife, giving it jurisdictional reach across Canada's principal regulatory, energy, and resource-development geographies.

The firm's professional team comprises 16 lawyers, of whom six hold the Environmental Law Specialist certification from the Law Society of Ontario, a credential the firm cites as the basis for its position as the largest private-sector environmental law practice in the private sector in Canada. The client base spans industrial companies, municipal governments, institutional clients (universities, hospitals), and First Nations and Métis communities, served through practice areas covering environmental compliance, contaminated land remediation, Indigenous consultation and duty to consult, energy project approvals, climate change litigation, and environmental due diligence in transactions.

Willms & Shier operates a traditional professional services revenue model based on billable hours for legal services, with engagement-specific fee structures negotiated individually with clients; pricing is not publicly disclosed. Its go-to-market is sales-led, driven by professional reputation, directory recognition (Lexpert, Best Lawyers, Who's Who Legal), published thought leadership, conference participation, and the Willms & Shier Environmental Law Moot — Canada's only national moot court competition devoted to environmental law. The firm is independently owned by its partner lawyers, with no external parent, private equity, or venture capital involvement.
