Mark St. Cyr

Partner | 

Mark St. Cyr (he/him/his) is a partner in the Construction Group at Cassels, where he provides strategic and practical legal advice to clients at any stage of any construction project. From initial concept, through design, procurement, and construction Mark advises clients on how to navigate and redistribute the risks arising in construction. With Mark’s broad drafting, negotiating, and solutions-driven experience, he has had the privilege of representing client on a wide variety of projects, across nearly every industry, throughout Ontario, the rest of Canada, and several other parts of the world. Mark’s practice includes both “front-end” project delivery advice and “back-end” dispute resolution.

On the front-end, Mark advises clients on the procurement and project delivery models that best suit their specific needs. He has drafted and negotiated all forms of agreements one might find on a construction project, including: stipulated price construction, GMP construction, cost-plus construction, master services, design-build, alternative financing (P3/PPP), engineering, procurement and construction (EPC and EPCM), integrated project delivery (IPD), engineering services, architectural services, “bridging” architect, construction management, and consulting services.

In addition to providing advice over the life of his clients’ projects, Mark also maintains a construction litigation practice where he represents clients on the “back-end” of projects during dispute resolution. Mark is active as both plaintiff’s counsel and defendant’s counsel in construction lien actions, bidding and tendering disputes, bond actions, breach of trust claims, and delay and deficiency claims. Mark’s approach to disputes is to identify opportunities for a commercially sensible early resolution, while at the same time mapping out the path for his clients to put their best foot forward at trial.
