He acts on behalf of general contractors, EPC contractors, owners, subcontractors, lenders and sureties in disputes arising from large-scale construction and engineering projects, primarily in the infrastructure, industrial and commercial sectors.

Jeff graduated from the University of Toronto Law School in 1981 and moved west to Calgary, where he joined Howard Mackie, becoming a partner in 1988. Howard Mackie merged with four other regional law firms in March 200 to form Borden Ladner Gervais LLP, which became Canada’s largest national firm.

Jeff has experience in the superior courts of Alberta, Saskatchewan and Manitoba, the Federal Court of Canada, and the Supreme Court of Canada, but his practice in recent years has become very much focused on arbitration, primarily as counsel. However, Jeff has also acted as an arbitrator in international and domestic disputes, and has taken engagements as a mediator.
