Philippe Tremblay



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

In the course of his practice, he has been the lead counsel in a number of complex commercial litigation files, many in the area of construction law. As such, he has acted in various files involving the different types of construction contracts (e.g., engineering, procurement and construction (EPC), engineering, procurement and construction management (EPCM) and public-private partnerships (PPP)). In the same context, he has also advised and represented both public and private contracting authorities regarding a number of different legal issues for purposes of preparing the call for tender documents and drafting and negotiating the contracts for the completion of various projects. Some of the projects he has acted in or clients he has represented include the Réseau Express Métropolitain (REM), the new Centre hospitalier de l’Université de Montréal (CHUM), the new Centre de recherche du CHUM and Énergir.

In this regard, Mr. Tremblay is the firm’s partner responsible for coordinating the external legal services provided by the firm for the REM project, the new CHUM project and the new CHUM research center. He also advises and represents these contracting authorities in relation to disputes and litigation arising from time to time in the process of implementing these projects, and in which the financial stakes are frequently high.

In addition, Mr. Tremblay has extensive experience with respect to the legal issues and disputes involved in the competitive bidding process, a field in which he has represented and advised many clients in the past, in various industries and regulatory contexts.

Furthermore, over the years, he has developed significant experience in expropriation matters as well as real estate law, and has been given the responsibility for a number of expropriation files, both by the expropriating authorities and the expropriated parties. Thus, among others, Mr. Tremblay has represented the CHUM (in an expropriation to allow for the construction of the new CHUM and its research center — a claim of more than $100 million) and Hydro-Québec. He also acts for the expropriated party in a major lawsuit against the STM involving a multimillion dollar claim.
