Commercial Disputes

Virtually any dispute involving a business relationship can end up in complex litigation.  Our approach is to narrow the dispute as quickly as possible, focus on key issues, and find solutions that recognize the practical realities of our client’s unique situation and the importance of preserving valuable business relationships where possible.  Among the myriad of complex commercial litigation matters that we regularly handle are the following:

  • injunctions, including seizures, Anton Piller applications and other urgent relief
  • unfair competition, unlawful interference with economic relations, breach of covenants
  • breach of contract
  • economic loss
  • shareholder disputes
  • property disputes including easements and rights of way
  • intellectual property disputes
  • partnership disputes

Our team has acted on the full range of disputes from filing and pursing builders’ liens on behalf of corporations through to claims arising from delay or defects involving hundreds of millions of dollars.

We routinely act for creditors, trustees, monitors, corporate debtors and receivers in insolvency litigation, bankruptcies, receiverships and CCAA proceedings.
