We offer strong, effective representation where workplace disputes arise and valuable insight into the best way to establish and implement realistic and reliable employment and labour practices.

Our lawyers understand the reputational risks inherent in implementing workplace initiatives.

U.S/Cross-Border Expertise

Our lawyers receive frequent inquiries about Canadian employment and labour law from U.S. counsel and clients. We have extensive experience guiding U.S.–based employers through downsizings, executive terminations and union organizing efforts, all of which raise different issues and require different solutions in Canada.

Executive Compensation

As part of our firm’s Executive Compensation Group, we help domestic and multinational businesses create appropriate employment arrangements for their employees and senior executives. We also advise boards of directors and their human resources committees in discharging their duties related to executive compensation matters.
