Dispute resolution in Canada

Baker McKenzie

Baker McKenzie has an emphasis on cross-border litigation and fraud-related disputes, with strong experience in advising major financial institutions on fraud, white-collar crime and financial recovery matters. The firm is also well versed in class actions, particularly multi-jurisdictional cases where it benefits from the ability to link up with its highly regarded global dispute resolution offering. Senior contacts include John Pirie, who leads the Canadian litigation and government enforcement group, and Matthew Latella. Up-and-coming partner Michael Nowina and talented associate Christina Doria are also recommended.

Practice head(s):

John Pirie


‘Baker McKenzie has the ability to understand and grasp in short time frames the strategic and operational issues facing the client when it has a potential dispute with the objective of first trying to resolve it prior to litigation. When there is to be hard fought litigation, the Baker McKenzie team provides a formidable defense. A real strength is the team’s ability to call upon other Baker McKenzie subject matter experts both nationally, and internationally to provide further necessary advice. The seamless approach ensures that Baker McKenzie’s client service is value added, timely, and cost effective.’

‘The team’s profile in Canadian courts is without a doubt a strength. The firm has defended Ontario judges in civil actions on more than one occasion. These engagements say a lot about the Baker team’s reputation among our bar and judiciary. The Baker team has showed an ability to quickly evaluate a case to provide strategic, business-minded advice. We trust their judgment implicitly when the stakes are high.’

‘I have worked with the firm for more than 17 years, and have chosen to work with them based on the group’s strong reputation in our Canadian courts. The Team is able to react quickly, make real time decisions and act with vigor in cases that are very challenging and free moving. When fraud or white collar crime is at issue, the Baker Team delivers the necessary actions to protect, and advance client interests and obtain such relief to give effect to these key facets.’

‘Partner John Pirie is the primary lawyer that I deal with on a regular basis. Mr. Pirie has a sterling reputation in our legal community. Mr. Pirie is regarded as a powerful litigator in the Ontario courts, particularly when it comes to white collar and fraud related matters. Mr. Pirie is one of the pre-eminent counsel to practice in Canada in this niche practice area. He takes a hands-on, in depth approach to identify the strengths and weaknesses of the case, and formulates a strategy that the Baker team will then implement with precision. He leads the Baker team in Canada, and has been instrumental in developing and fostering the team’s profile in Canadian courts which is without a doubt a key strength. Mr. Pirie can deliver timely and effective results to achieve client goals and protect against financial loss, by quickly putting together the necessary proceedings – motions, injunctions and the like.’

‘David Gadsden is thorough, practical and able to identify the key issues at hand and then devise the necessary strategy to achieve client objectives.’

‘Matthew Latella is a formidable opponent who is able to advocate key submissions in a persuasive and comprehensive manner designed to reach the Court’s attentions and concerns.’

Matthew Latella assisted our client in a hard fought battle up to leave to appeal to the Supreme Court. He is a technically superb, impressive advocate. He was an absolute pleasure to work with and provides first-rate advice and support.

‘Known for high level expertise in cross-border litigation, particularly in fraud and asset recovery matters (both plaintiff and defense side). They have acted as counsel on some of the main fraud related decisions in Canada including notable matters in the securities, competition and insolvency contexts. They have also made law in Canada when it comes to enforcement of foreign judgments and arbitral awards, particularly in a fraud context.’

‘My impression of the team as a whole is that it is excellent. The team is masterful in achieving successful outcomes for their clients in high-stakes litigation. They tackled a high-profile international trial, that few counsel will get to see in their careers, with mastery and aplomb. It is clear that each member of the team brings knowledge, expertise and valuable skills to the table, and that the global team works together seamlessly for the client.’

‘The primary lawyers I dealt with were John Pirie and the Canadian group. They are well known for handling corporate fraud matters, particularly those with international aspects. This high-level expertise has been readily apparent throughout my work with Baker McKenzie.’

‘John is an experienced litigator with deep expertise in several areas including class actions and cross-border litigation. He is a brilliant strategist with an unparalleled ability to bring clarity and big-picture perspective to even the most complex litigation matters. Moreover, John is an astute and skilled litigator and excellent leader, having instructed the joint trial team every step of the way, leveraging each member.’

Practice head(s):

Gordon Tarnowsky QC


‘The advice I routinely receive is practical and ethical, and factors in potential process costs of various scenarios. I’ve found Dentons to be particularly judicious about ensuring not just that the outcome of a particular file is good but that we reach that outcome in the most cost-effective way – this is a very consequential thing when a file involves multiyear, nine-figure disputes. I’ve also never had occasion to question the reasonableness of a Dentons invoice. I say this having worked with several other firms, including with other national and international firms.’

‘Dennis Picco handles the majority of my most complex commercial matters and has very much become a ”trusted advisor” for both business and legal strategy. Cristina Wendel has also been for several years a ”trusted advisor” with respect to any labour or employment matter. Her advice is sound, thoughtful, and practical.’

‘Amjad Khadhair and Simon Elzen-Hoskyn have, as associates, worked on several of the more difficult matters we’ve handled. Their involvement gives me comfort that issues have been thoughtfully and thoroughly considered. I’ve come to trust their analysis and recommendations.’

‘The success of a team is greatly the ability to assign the right people to do the right tasks, and ensure the (common) goal is fully understood and communication is constant. In the mandate that we gave to Dentons, that ability was clearly demonstrated.’

‘Dentons has a team with good familiarity of the ICSID arbitration methods and procedures and a good support team here in Calgary who well understand the oil and gas industry.’

‘Denton’s team are meticulous and understand the importance of limiting the budget to contest our arbitration proceedings.’

‘Excellent legal analysis and advocacy Prompt action and careful attention to details. Very good client management and result oriented. Top echelon relative to other firms.’

‘David Wotherspoon is very knowledgeable of the law and strategies. Great leader and delegates work as appropriate to get the best result for the clients at the least cost. Top draw in Intellectual Property.’
