Colm St. Roch Seviour, QC


“Just do it.” (Whether at the beginning of a case, at the line of scrimmage, on top of a mogul field, or on the tennis courts.)


Clients nowadays have different requirements: time sensitive needs for top quality legal advice from counsel who know their business objectives and the real-world landscapes in which they operate. With almost 30 years of practice and experience in the areas of natural resources, environmental, products liability and commercial litigation, Colm brings veteran analysis and timely, practical solutions to his clients.



Working with a diverse group of clients that include prospectors, mining firms, onshore and offshore oil and gas operators, hydroelectric project developers and product manufacturers, Colm helps to protect interests and achieve results. He has acted as counsel in:
  • Numerous Newfoundland and Labrador mining and other natural resources transactions
  • Mining royalty arbitrations under the International Commercial Arbitration Act
  • Litigation of aboriginal rights claims (including CEPA, Fisheries Act, and provincial environmental legislation)
  • Defence of environmental charges
  • Prosecution and defence of product liability claims involving products as diverse as hockey skates and offshore heat tracing
  • Commercial mediations and litigations in matters ranging from simple contract breaches to civil fraud
  • NAFTA matters, including acting as lead NL counsel for AbitibiBowater Inc. in its 2009 case against the Government of Canada, resolved by settlement in 2010

Colm has litigated cases before the NL Mineral Rights Adjudication Board and the NL Public Utilities Board, at all levels of the NL Courts, and in the Supreme Court of Canada.
