Mark St. Cyr

Partner | 
Toronto

Mark St. Cyr is a partner in the Construction Group at Cassels. Mark provides strategic and practical legal advice to clients at any stage of any construction project. From the initial design concept, through procurement and construction, all the way through to project completion, Mark advises clients on how to navigate and re-distribute the inevitable risks that come with construction. With Mark’s broad drafting, negotiating, and risk distribution experience, he has had the privilege of working 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 the following forms of agreements: 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 project 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 time mapping out the path for his clients to put their best foot forward as plaintiff or defendant.

Mark acts for clients at all levels of the “construction pyramid” and across multiple industries. Currently, Mark counts owners from a wide variety of sectors as clients, including some from academia, financial institutions, municipalities, and several TSX listed mining companies. Mark is also currently retained by several contractors, subcontractors, material suppliers and he has even counted a few engineering firms as his clients in the past.

Prior to becoming a lawyer, Mark was a crime analyst with the Royal Canadian Mounted Police, based in North Vancouver, British Columbia.
