Lorne Rollheiser

Lorne Rollheiser is a partner in Gowling WLG's Calgary office and head of the firm's Canadian Oil & Gas Industry Group. Lorne is also a member of the firm's Canadian Hydrogen, Bio-Gas/Ag Energy, and ESG sub-sector groups.

Lorne has more than 20 years of experience practising in natural resources and energy law — including as in-house counsel with two of North America's largest independent oil and gas producers. This unique background positions him strongly in the market and equips him to offer sophisticated legal advice that's in tune with the day-to-day realities of the sector.

Working closely with domestic and international exploration and production clients, Lorne focuses his practice on a range of complex energy-related matters associated with the planning, development, and execution of upstream and midstream projects. With respect to upstream projects, Lorne has significant experience advising on matters concerning seismic acquisition and use, regulatory approvals, surface and mineral rights, farm-ins, joint ventures, accounting and royalty issues. In the midstream and downstream space, he advises both shippers and carriers across an array of different areas, including transportation service agreements, tariffs, buy/sell arrangements, regulatory approvals, blending and optimization deals, and commodity trading agreements.

Over the course of his career, Lorne has also led teams in a multitude of high-stakes merger & acquisition and amalgamation & divesture transactions — both domestic and international. Representing buyers and sellers alike, Lorne helps clients manage the sales process, conduct due diligence, coordinate the submission or receipt of bids, and negotiate and draft definitive purchase and sale agreements.

Recognized by The Legal 500, Canadian Legal Lexpert Directory and Best Lawyers in Canada as a leader in his field, Lorne's A&D and M&A deal history, upstream and midstream activity, and project development experience make him a valued leader at Gowling WLG and an exemplary adviser to clients in the natural resources and energy sectors.
