Greg Hersen plays a pivotal role at Torkin Manes as the leader of the Construction Law Group. His expertise has been officially recognized by the Law Society of Ontario, which designated him as a Construction Law Specialist back in May 2001. His excellence in this field has been consistently acknowledged since 2017 by The Best Lawyers in Canada© and he's been lauded by peers within the Canadian Legal Lexpert Directory. His leadership in Construction Law was highlighted in the Lexpert Special Edition focusing on Canada's Infrastructure lawyers, and he boasts a Distinguished Peer Review Rating from Martindale-Hubbell.

Throughout the construction project lifecycle, Greg offers strategic counsel to a diverse client base, including public and private sector entities, general contractors, sureties, subcontractors, suppliers, and design professionals. His projects span a wide array of public infrastructure ventures, such as transit systems, bridges, and flood management systems, as well as private developments in sectors like industrial, commercial, and residential real estate, and mining.

Greg's guidance covers a broad spectrum of construction-related challenges, from delay and tender disputes to lien claims, negligence, contract issues, COVID-19 related claims, and more. His approach encompasses courtroom advocacy across trial and appellate levels, alongside a strong emphasis on Alternative Dispute Resolution (ADR) techniques like negotiation, mediation, and arbitration.

Significantly, Greg has the distinction of being the first lawyer appointed to the Canadian Construction Documents Committee (CCDC), contributing over a decade to the refinement and creation of key CCDC construction documents. His drafting skills extend to tender documents, construction and professional service contracts, and he is well-versed in ensuring compliance with Ontario’s Construction Act, focusing on issues like prompt payment and holdback release.

Greg is an authoritative voice in construction law, frequently leading discussions at industry seminars on cutting-edge topics, including design/build and construction management contracts, delay claims, and the CCDC construction documents. His educational contributions also include presenting Continuing Legal Education Programs for prominent legal associations in Ontario and Canada.

His legal credentials are solid, highlighted by his certification as a Construction Law Specialist, admission to the Ontario Bar in 1991, and degrees in law and arts from the University of Windsor and the University of Western Ontario, respectively. Through his deep involvement in construction law, Greg has become a trusted advisor and a leading figure in navigating the complexities of construction projects and disputes.
