Devon Lehrer
Camila Carvalho


Devon’s practice is focused, primarily, on construction litigation. He acts for developers, owners, contractors, professionals and trades in all manner of construction disputes including payment disputes, deficiency and delay claims, professional negligence claims and builders lien matters.

Taking a practical, pragmatic and proactive approach to disputes, Devon confidently navigates both the traditional litigation framework and employs alternative dispute resolution methods to steer matters towards an advantageous outcome for his clients.  Devon is also experienced in preparing and reviewing a broad range of contracts and documents and is more than happy to assist clients before they find themselves in a dispute.

Devon has represented clients in the Supreme Court of British Columbia, Provincial Court of British Columbia and before various administrative tribunals. A regular guest speaker, Devon frequently leads educational sessions for construction professionals.

Away from the office, Devon can most often be found enjoying time with his wife, their two young daughters and their grouchy old dog. When he has a free moment, Devon enjoys cycling, skiing, and golf.
