Brendan D. Bowles




Brendan Bowles is devoted to providing first rate client service and advice. Since joining the firm in 1998 he has specialized in the practice of construction law. He is fortunate to be supported at Glaholt Bowles by a team of outstanding support staff, students, associates and partners, all of whom share his dedication to client service and excellence in the practice of construction law.

Brendan has experience as team leader in all manner of construction related disputes and contract issues. Construction and infrastructure projects are technically complex, document heavy and relationship driven. Resolving disputes and solving problems requires specialized knowledge of the law and a team who is prepared to understand and prioritize the client’s business concerns and strive for strategic solutions to legal challenges. Brendan is prepared to “go the distance” when necessary, but the team at Glaholt Bowles will always challenge themselves to find creative, proportionate resolutions that allow their clients to get back to business. 

Brendan’s expertise and high standards of practice have been recognized by his peers; he is rated as “Most Frequently Recommended” in construction law by Lexpert, and is also the 2021 recipient of the Ontario Bar Association’s Award for Excellence in Construction and Infrastructure Law. He is also certified by the Law Society of Ontario as a Specialist in Construction Law. In 2004 he was designated as an Associate in Canadian Surety Bonding by the Surety Association of Canada. From 2002 to 2017 he volunteered on the Executive for the Construction and Infrastructure Law Section of the Ontario Bar Association, serving as Chair of the Section in 2015–2016. Brendan was formerly a lecturer in construction law at Ryerson University and George Brown College and has also served as a guest lecturer at the University of Toronto, Faculty of Law. Presently, he is Vice-Chair of The Advocates’ Society Arbitration and Mediation Practice Group, and editor of the Canadian College of Construction Lawyers' Legal Update newsletter

Outside of the office, Brendan is a volunteer youth hockey coach and has also completed marathons, including the Toronto Marathon and Marine Corps Marathon.
