Philippe Tremblay



Philippe Tremblay has been practising commercial litigation since his admission to the Bar in 1987.

In his many years of practice, he has led numerous complex commercial litigation files giving rise to a number of construction law remedies. He has acted in various public-private partnership construction files, and has been called upon to advise and represent public authorities regarding many aspects of these cases, among which, the preparation of invitation for proposals documentation as well as the drafting and negotiation of partnership agreements, including the new Centre hospitalier de l’Université de Montréal (CHUM) and its new research center.

Mr. Tremblay is the firm’s partner responsible for coordinating the external legal services required by the CHUM to ensure the modernization and redevelopment of the new hospital and research centers by way of a public-private partnership. In that capacity, he coordinates and manages the legal work in order for the CHUM to benefit from a legal support with respect to the negotiation and conclusion of partnership agreements with private partners as well as the construction of new buildings and the negotiation of many related transactions with municipal and government authorities as well as with private parties. He also represents the CHUM with respect to litigation matters that arise in connection to this project, including a major dispute involving tens of millions of dollars.

Mr. Tremblay spearheaded the preparation of a call for tenders and drafted the contract documentation for a major Gaz Métro project, valued at $800 million, involving the construction of a 450-km gas pipeline connecting Jonquière to Sept-Îles, in Northeastern Québec.

Mr. Tremblay also has extensive experience with the legal issues involved in the competitive bidding process and litigation relating to that process, a field in which he has represented and advised many clients in various industries and regulatory contexts.

Throughout the years, Mr. Tremblay has developed a solid experience in expropriation and real estate law. He has been the lead counsel in many expropriation files, representing both expropriating authorities and expropriated parties. As such, he represents the CHUM (expropriation in order to allow for the construction of the new CHUM and its new research center  - claims in excess of $100 million) and Hydro-Québec. Mr. Tremblay also acts for the expropriated party in a multimillion claim against the STM.
