The environmental law practice at Torys is ‘well-informed, up-to-date and strategic’. Demonstrating strong skill sets across all relevant industries, including energy and natural resources, transport, infrastructure, chemicals and consumer products, the team is particularly distinguished by its expertise in nuclear-related matters. Toronto’s Dennis Mahony chairs the practice and acted alongside the litigation group to represent Canadian National Railway on a judicial review of the federal environmental process in connection with its Milton Logistics Hub. The group also includes Toronto-based Michael Fortier, who is recognized for his record in the nuclear sphere; Toronto’s Tyson Dyck, who specializes in climate change law; and Calgary-based Lou Cusano, who is noted for energy-related work.
