Insolvency and Restructuring

Wooden puzzle.

Osler’s Insolvency & Restructuring Group is Canada’s leading multi-disciplinary practice offering top-tier legal expertise in all aspects required to resolve the most compelling business challenges. Our team based, multi-disciplinary approach delivers innovative and integrated solutions for complex business-critical matters and has been ranked Band 1 in Chambers Canada, one of the world's leading legal directories. Osler succeeds for several reasons:

  • Diverse Clientele and Wide-Ranging Scope. We act for all types of clients dealing with challenging business circumstances and deliver leading-edge counsel in complex matters throughout the North American economy. We are relied upon as tested and trusted advisors to directors, senior executives, in-house counsel, credit and investment officers and fund managers, as well as other professional advisors, court-appointed officers and regulators. In addition to providing advice and leadership in distress situations, we are frequently consulted on mergers & acquisitions, securitizations and derivatives, credit matters, supply chain management, financial reporting and governance in business-critical situations.
  • Multi-Disciplinary Approach. Solving complex business challenges requires an integrated application of expertise and perspective across many different disciplines. Osler’s Insolvency & Restructuring practice is based on a multi-disciplinary approach that draws upon market leading resources throughout the Firm to deliver integrated solutions seamlessly and effectively to meet the needs of any business-critical situation.
  • Cross-Border Strength. We have extensive relationships with U.S. based advisors and have earned a leadership position in crafting comprehensive cross-border solutions in North America. We were among the first counsel globally to structure cross border protocols governing administrative process, substantive treatment and court-to-court communications in international insolvencies and we continue to be leaders in North America in that regard.
  • Scalable Staffing with Deep Expertise. We invest heavily in the training and development of our personnel and have built a dedicated team with rigorous standards and market leadership for over 30 years. Our clients gain the benefit of a professional “depth chart” at varying levels of seniority that allows us to tailor the team to meet the demands of any business-critical situation in a cost-effective manner while providing innovative solutions that only deep expertise can. That experience and expertise allow Osler to deliver practical, commercially achievable solutions to compelling business challenges.
  • Rapid Response. We engage quickly, efficiently and effectively to meet the needs of any business-critical situation, regardless of the level of complexity.
