Glenn Ackerley is the Chair of the Construction Practice Group at WeirFoulds. His practice is focused on construction law, construction liens and construction litigation.
Glenn fills the role of a “project lawyer”, providing ongoing advice from the start through to completion of a project. He represents clients from across the construction industry – including public and private owners, developers, contractors, subtrades, suppliers, and consultants – in a variety of construction-related matters.
He is regularly consulted about negotiating and preparing construction and consultant contracts, procurement and tendering issues, and risk avoidance strategies. When disputes arise, Glenn acts for clients from both the ICI and residential sectors in construction lien and trust claims, bond claims, and construction delay and deficiency claims.
Glenn is active in the industry, participating on boards, committees and working groups to support and improve the industry. Glenn sits on the National Advisory Council of the Canadian Construction Association and is a past member of its Board of Directors, and is a Past Chairman of the Board of the Toronto Construction Association. He sat on the Executive of the Construction Section of the Ontario Bar Association for many years, and most recently has been a member of the Expert Panel’s Advisory Group on changes to Ontario’s Construction Lien Act.
He developed and taught the Construction Law course at the Department of Architectural Science of Toronto Metropolitan University (formerly Ryerson University) for many years. The course covered a whole range of issues, including contract and negligence law, tendering, construction liens, damages and dispute resolution. He has written several published articles and given presentations on legal topics to both industry and legal groups, including seminars at the Ontario General Contractors Association’s Symposiums and the Admission Course of the Ontario Association of Architects.
Appreciating the important role played by alternative dispute resolution, Glenn has trained and gained experience in both mediation and arbitration, acting as counsel, mediator and arbitrator.
