About our Litigation & Dispute Resolution Group
With an impressive track record in domestic and cross-border litigation, McMillan’s 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, our litigators always strive 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.
Formerly a prominent regional insurance defense firm, Vancouver-founded Whitelaw Twining has seen impressive growth in its near 45-year history. From establishing a strong corporate-commercial litigation practice, to expanding across Canada, to becoming part of DWF Group and its global network, our milestones reflect our continuing commitment to scale and innovate to better cater to our clients’ diverse needs and growing lines of business.
With offices in Vancouver, Calgary, Toronto and Montreal, and with capabilities to serve further provinces and territories, our team of over 130 professionals pushes beyond standard litigation practices to deliver progressive and creative solutions in complex, high-stakes and multi-jurisdictional disputes. Our culture is one of collaboration, and we combine local knowledge with global resources to achieve success for our clients.
We work closely with each client to determine their particular needs and employ a results-driven approach to ensure strategic alignment with our clients’ long-term goals. Our team skillfully and tactfully advocates for our clients in the courtroom, before various regulatory bodies and tribunals and in arbitrations and mediations.
With an eye on data and analytics, we maintain metrics that assist us with and inform our clients of our ongoing evaluation and improvement of cost-efficiency, cycle times and general file-handling procedures.
We value being a good corporate citizen. Our lawyers actively participate in their local business and social communities. We support and enthusiastically volunteer with access to justice organizations and community outreach programs and devote time to lecturing at universities and hosting informational seminars on current industry topics.
