Our firm values – respect, teamwork, commitment, client service and professional excellence – are at the heart of McMillan’s commitment to serve our clients, our local communities and the legal profession.

McMillan’s Litigation & Dispute Resolution Group is one of Canada’s leading domestic and cross-border corporate commercial litigation firms. Our lawyers are recognized for their creativity and effectiveness in bringing disputes to satisfactory conclusions, both inside and outside the courts. And with specialists in key areas such as competition, intellectual property, real estate, securities and others, McMillan’s Litigation & Dispute Resolution Group always strives to deliver a complete solution – no matter the nature of your corporate or commercial disputes. 

As experienced litigators, we always assess risk and opportunities before advising clients on the likelihood of success and helping them weigh their options. We also understand that litigation is not always the preferred option, and help clients pursue a full range of resolution avenues including early negotiated settlements and alternative dispute resolution methods. If we proceed to court, however, we are recognized for our ability to tenaciously advance our clients’ commercial interests.
