An experienced environmental and climate change lawyer with deep involvement in the energy, infrastructure and mining sectors, Tyson brings strategic acumen, skillful advocacy and technical insight to his work advising clients on the their most complex matters.
In the energy sector, Tyson provides critical guidance to clients as they navigate the energy transition. He has advised on many of North America’s most high-profile energy projects, including on the development, permitting and financing of more than 50 wind, solar, gas, hydro and energy storage projects, together representing over 7,000 MW in installed capacity. He also advises on major transmission and distribution projects, including electricity transmission lines and natural gas pipelines, and some of the world’s largest Carbon Capture, Utilization and Storage (CCUS) projects. Tyson gives strategic advice in navigating complex and often challenging environmental assessment and permitting processes, as well as on negotiations with regulatory agencies, Indigenous communities, local municipalities and other stakeholders.
Tyson also leads the firm's Climate Change Practice. He has decades of experience in the area, having worked on some of the country's earliest carbon offset deals and emissions reduction funds. He now advises clients with responsibility for over 100,000 kilotonnes of GHG emissions as they transition to a low-carbon economy. He is regularly retained to advise on the development of carbon trading and compliance strategies, on agreements for the purchase and sale of emissions reduction and clean energy credits (in both compliance and voluntary markets), on the development and marketing of carbon offset and removal projects, and on climate change disclosure issues (both under evolving securities laws and voluntary reporting frameworks such as the GHG Protocol and the Task Force on Climate-Related Finance Disclosures). He is currently helping some of the country's largest companies in developing their strategies to achieve Net Zero GHG emissions.
In the mining and metals sector, Tyson acts for companies acquiring, financing, developing and operating major uranium, potash, coal and precious metals operations across the country. He regularly advises these clients on stakeholder relations and permitting, compliance and enforcement matters, including investigations and prosecutions under provincial and federal environmental laws. He has also worked with national and provincial industry associations on strategies to address environmental risks and seize climate change-related opportunities.
Tyson advises clients in many other sectors, including pulp and paper, water treatment, communications, iron and steel, chemicals and manufacturing. He provides advice on the full range of issues in the environmental and energy-regulatory fields, including environmental assessments, project permitting, contaminated sites remediation, endangered species protection, spills response and reporting and the inspection, investigation and defence of environmental offences. As a co-leader of the firm's ESG Practice, he also regularly advises on high-stakes, reputationally sensitive ESG issues for major financial institutions, investors and asset managers.
