Brendan D. Bowles



Brendan Bowles is devoted to excellence in client service in the practice of construction law. Since joining the firm in 1998 he has had the privilege of ongoing mentorship of leaders in the field, not only through his practice at Glaholt & Associates and Glaholt Bowles LLP, but also through 15 years of volunteering with the Executive of the Ontario Bar Association’s Construction and Infrastructure Law Section, and now through fellowship in the Canadian College of Construction Lawyers. At Glaholt Bowles he is fortunate to be supported 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 projects are technically complex, document heavy and relationship driven. Resolving disputes and solving problems requires 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. 

Outside of the office Brendan is a volunteer youth hockey coach with both the Etobicoke Dolphins Girls’ Hockey League and the George Bell Hockey Association. He is also a marathon runner: completed races include the Toronto Marathon and Marine Corps Marathon.
