Construction Litigation

Bridge construction

The COVID-19 pandemic, global uncertainty and rising inflation have all posed challenges to the construction and infrastructure industry in recent years. Today’s projects face different obstacles than they did even a few years ago, and tailored dispute resolution from specialized legal professionals is more important than ever.

From the early planning, project structuring and financing stages to procurement, construction and contract management, Osler’s integrated team of construction lawyers is available to get your project off on the right foot — or, if necessary, help to get it back on track.

Industry experience

Construction law is a highly specialized field, with its own unique dynamics, interests, statutes and regulations. Osler’s construction litigation team consists of specialized construction disputes experts who are familiar with a range of creative dispute resolution mechanisms, as well as the nuances of the construction lien legislation across Canada.
