Mark Andre St. Cyr

Mark St. Cyr (he/him/his) is a partner at Cassels in the firm’s national Construction Law Group. He also sits as a member of the Infrastructure Law, Mining Law, and Higher Education Law groups, where he is sought after to facilitate the development of bespoke solutions for construction projects across industries. From the initial concept, through financing, design, procurement and construction, Mark advises clients across Canada and internationally on how to navigate and redistribute project risks.

Mark’s practice includes both “front-end” project structure, delivery, and transaction advice, as well as “back-end” dispute management and mitigation.

Mark’s primary focus is on the “front-end” where Mark advises clients on project structure, procurement, and project delivery models, identifying the best contractual model to suit their project. Mark has the proven ability to turn complexity into concise and straightforward solutions. In addition, he has extensive experience drafting and negotiating all forms of construction agreements, as well as new, innovative, and complex contracts such as alternative financing (P3/PPP), alliancing and integrated project delivery (IPD), progressive delivery models (design-build and construction management), “design-assist,” and “bridging” agreements.

Mark also helps clients navigate in-project and post-completion disputes. As a solutions strategist, Mark is regularly sought out to assess the merits of complex disputes with a view to developing the best go-forward strategy given the strengths and limits of his client’s position as well as their commercial needs. This approach has kept Mark in high-demand to advise both claimants and defendants in a variety of unique construction-related disputes, including integrated project delivery disputes, procurement disputes, bond claims, as well as delay and deficiency claims. Mark’s approach to disputes is to resolutely advance the position of his clients to set up success at trial, while also identifying opportunities for a commercially sensible early resolution.
