As a destination practice for oil and gas clients, Bennett Jones LLP is one of the few firms equally equipped to handle major energy transactions as well as complex regulatory matters, including industry-shaping litigation. The Calgary-based team is routinely engaged by the full spectrum of stakeholders, from emerging independent producers and operators, through to global industry players and government entities. Among its recent M&A mandates, high-profile department co-head Patrick Maguire acted alongside corporate partner Ashley White to advise Canada Oil Sands on the sale of its equity interest in Japan Canada Oil Sands, which has a 75% working interest in the Hangingstone Oil Sands Project. Luke Morrison is also a key contact for oil and gas transactions. A deep bench of regulatory specialists is anchored by department co-head Shawn Munro, who is highly regarded for environmental law. Other recommended names for regulatory work include Lawrence Smith KC, Martin Ignasiak and Sean Assié. Brad Gilmour joined Osler, Hoskin & Harcourt LLP in February 2024.
