Ralph Cuervo-Lorens

In his litigation practice, Ralph focuses on regulatory, risk management and compliance matters, together with all aspects of dispute resolution and advocacy. He acts as lead counsel in the management and resolution of complex business and regulatory matters across a broad spectrum of law, including commercial, corporate, environmental, financial advisory, anti-corruption, privacy and freedom of information, first nations, tax, securities and white-collar fraud.

He regularly advises a wide range of clients including mining, property developers, energy, services (financial, consumer, retail) and manufacturing.

Ralph’s regulatory practice has a focus on CSR standards, social license to operate and environmental risk-management and compliance for clients with “high impact” businesses. His work in this area  includes traditional regulatory matters (such as impact assessment, disclosure and reporting, decommissioning, Aboriginal consultation and accommodation, audits, risk management, emergency response and remedial and clean-up plans) and also extends into due diligence, risk management and disclosure issues in corporate securities, financing and mergers and acquisition transactions.

Ralph has acted as Settlement Counsel in multi-party litigation, is Associate Member of The Chartered Institute of Arbitrators (U.K.) and has been Court-appointed Independent Counsel in complex litigation. He is co-author of the leading Canadian text on tax evasion.

Ralph also acts as defence counsel in regulatory and quasi-criminal prosecutions under a wide range of federal and provincial regulatory and taxation statutes. Ralph has appeared or made representations on matters for clients before the Environmental Review Tribunal, Ontario Municipal Board, Information and Privacy Commissioner, Ontario Securities Commission, Walkerton Public Inquiry, Health Services Appeal Board, various municipal councils, Tax Court of Canada, Federal Court of Canada, Ontario Provincial Court, Ontario Superior Court of Justice and the Court of Appeal for Ontario.
