Litigation & Dispute Resolution

WeirFoulds has one of the premier litigation practices in Canada and is well-versed in handling high-stakes and highly publicized litigation. We appreciate how much is at stake in our clients’ cases, and we rigorously defend our clients to maximize their odds of success.

Over the course of the 19th, 20th and now the 21st centuries, WeirFoulds has been privileged to have acted on ground-breaking cases in almost every area of civil litigation. For generations, our lawyers have been regarded as leaders of the bar and of the legal profession. For everything there is a reason: in our case, we have always brought and always will bring the highest level of advocacy skill to every engagement. This expertise includes the ability to provide sensitive and timely advice on complex litigation — such as class actions — the management of document intensive litigation, lengthy multi-party trials, and the development of innovative legal solutions short of litigation.

Our litigators have extensive experience arguing complex cases before trial and appellate-level courts. We represent government entities, public and private companies, civil organizations and individuals in an array of corporate, commercial, intellectual property, class action, employment, securities, tax, Aboriginal, defamation, estates and trusts, administrative, energy, environment, competition and constitutional law disputes. Our litigators have appeared before all levels of courts and a host of regulatory boards and tribunals.

We draw on our deep institutional knowledge of litigation procedure and strategy, as well as sophisticated in-house and external resources, to resolve disputes efficiently and effectively. Among other things, we use our e-Discovery team to handle voluminous documentation resourcefully, and we explore alternatives to litigation proceedings – including mediation and arbitration – wherever possible.
