Tyson Dyck is a member of the firm’s Environmental Group, and practises extensively in the areas of Energy and Infrastructure, Mining and Metals and Climate Change. He has been recognized in Chambers Global and Chambers Canada as a leading lawyer in environmental law, and in Who's Who Legal as one of the world's leading climate change lawyers. The firm’s Environmental, Infrastructure and Energy groups have also been consistently recognized among Canada’s leading and most frequently recommended practices, including by Chambers & Partners, Practical Law Company and the Canadian Legal Lexpert Directory.

In the energy sector, Tyson has worked extensively on the development, permitting and financing of generation, transmission and distribution projects across Canada, including well over 50 wind, solar and hydro projects, together representing over 4,000 MW in installed capacity; Ontario’s largest natural gas-fired generators; and numerous intra-provincial and international electricity transmission lines and natural gas pipelines. Tyson provides strategic advice to these clients in navigating complex and often challenging environmental assessment and permitting processes, and frequently advises on negotiations with regulatory agencies, Aboriginal communities and local municipalities.

In the mining and metals sector, Tyson acts for companies acquiring, financing, developing and operating major uranium, potash, coal, precious metals and other extractive operations. He regularly advises these clients on stakeholder relations as well as permitting, compliance and enforcement matters, including under the Fisheries Act and Metal Mining Effluent Regulations.

Tyson also has significant expertise on climate change policy and regulation, particularly on the cap-and-trade systems established in Ontario, California and Quebec and other jurisdictions. He has advised some of Ontario and Canada's largest greenhouse gas emitters on the formation of and compliance with cap-and-trade regulations, the development and financing of emissions offset projects, and compliance with climate change-related disclosure requirements. Tyson regularly publishes in these areas and has presented extensively on climate change issues, including at Stanford Law School and the University of Toronto Law School.

Tyson has also advised regional and national industry associations in both the energy and mining sectors on major environmental developments. He also 
advises clients in many other sectors, including clients in the pulp and paper, water treatment, communications, iron and steel, chemicals and manufacturing.

More generally, Tyson’s practice covers the following areas:

  • Project development advice: Tyson provides strategic advice on the development, permitting, purchase, sale and financing of high-profile and often contentious projects, with a focus on energy, mining and other infrastructure projects.
  • Regulatory advice: Tyson provides strategic advice on the full range of issues in the environmental, health and safety and energy-regulatory fields, including federal and provincial environmental assessments; environmental permitting; energy-regulatory system compliance; contaminated site remediation; spills response and reporting; species-at-risk matters; and the response to orders, investigations, prosecutions and other regulatory compliance matters.
  • Administrative hearing advice: Tyson has also advised clients on dozens of proceedings before the Ontario Energy Board, Environmental Review Tribunal, Canadian Nuclear Safety Commission, National Energy Board, Niagara Escarpment Commission and other administrative tribunals.
  • Transactional advice: Tyson assists buyers, sellers, lenders and investors through all of the environmental, health and safety aspects of a transaction. In a typical year, the firm’s Environmental group is involved in more than 100 commercial transactions.
