Osler’s National Construction and Infrastructure Group team works with Canadian, US and international clients to help ensure the success of their projects. Our dedicated team of lawyers have deep experience in large, complex projects and provide our clients with expert advice throughout the full life cycle of their construction and infrastructure projects.   

Unlike many other law firms, our Construction and Infrastructure Group comprises specialized solicitors and litigators who work together to deliver construction legal services from the front-end of a project right through to its conclusion. A number of lawyers in our Construction and Infrastructure Group are also professional engineers and offer practical experience and knowledge of the construction industry. As a result, we have gained invaluable insights into the required work, scheduling, cost, disputes, and other issues typically associated with the development and construction of a complex project.  

Our team works with a broad range of industry participants including owners, developers, contractors, sub-contractors, lenders, construction managers, architects, engineers and consortia bidding on the construction and development of commercial/industrial infrastructure. We provide advice on all types of commercial, industrial and institutional construction projects and mega projects, including energy (on-shore and off-shore wind, solar, oil sands, nuclear and LNG), infrastructure developments, public-private partnerships (P3), alternative financing and procurement, health, transportation and other projects.

With our decades of experience and breadth of exposure to a large number of projects across many industries and jurisdictions, Osler brings unmatched insight and business acumen to project structuring, risk identification and allocation, financing, contract negotiation and documentation and dispute resolution.

Clients come to Osler for construction advice for the following reasons:

  • Technical and Commercial Knowledge. A number of our lawyers hold both law and engineering degrees and have hands-on project experience.  As a result, our clients receive technical excellence and commercial law know-how on their most important matters.
  • Understanding Project Risk. We achieve the results our clients expect on their projects by understanding the risks and providing practical advice and representation within the context of the current market.
  • Litigation and Mediation Expertise. Our fully integrated construction litigators provide mediation, arbitration, litigation and other alternative dispute resolution advice on the construction process. We have intimate knowledge of the Construction Lien Act and have appeared at all levels of the courts. We understand how to quickly and effectively navigate the system to get a project back on track and achieve the results our clients want.
  • National and U.S. Expertise. Osler can tailor services to the specific needs of our clients by drawing on a full range of project development and litigation services in our Toronto, Montréal, Calgary, Ottawa and New York offices.

Our team is active in the Canadian construction industry and are members of organizations such as the Ontario Bar Association Construction & Infrastructure Section, the Law Society of Upper Canada, the Canadian College of Construction Lawyers, the American Bar Association Forum on Construction Law, Professional Engineers Ontario, and the Canadian Council for Public-Private Partnerships. Our lawyers closely monitor the industry and regularly speak and write on issues, trends and legislative changes that may affect our clients.
