Striking a balance between front-end work and litigation, Dentons’ construction practice is valued for its ‘incredible ability to understand and provide legal solutions to varying commercial concerns’. In the non-contentious space, the group’s broad industry experience spans the full range of project structuring, procurement and implementation, with Vancouver-based department co-head Jana Mansour highly regarded in this sphere. On the contentious side, Vancouver-based co-lead Karen Martin KC is widely recognized as a market leader for construction disputes. The team also benefits from the senior experience of Edmonton litigator Dennis Picco KC; Vancouver-based construction, infrastructure and procurement specialist John Haythorne; Montreal’s Pierre Grenier, who is noted for contentious construction cases; and Toronto-based Karen Groulx, who advises on construction contracts and dispute resolution. Edmonton associate Robert Gilroy is also recommended for construction disputes.
