Practice areas
Criminal trials and pre-charge advocacy
Counsel steps in before charges are laid to try to prevent them and to negotiate with prosecutors. If charges follow, the firm's lawyers defend criminal and regulatory cases, whether the issue is an administrative decision or a very serious offence. William Thompson's trial work covers impaired driving and similar traffic charges.
Professional liability and regulation
The firm defends doctors, nurses, lawyers and other licensed professionals in discipline proceedings, including Law Society of Ontario matters, and also acts as prosecutor for regulators. Clients get counsel who has worked on both sides of these files.
Commercial litigation
Hundreds of trials and appeals sit behind the firm's work on high-stakes business disputes, covering contract disagreements, negligence, shareholder and oppression claims, and professional liability.
Securities litigation
When the Ontario Securities Commission or IIROC brings a claim, the firm acts for the individuals and organizations on the other side.
Injunctions
Urgent work covers freezing (Mareva), civil search (Anton Piller) and third-party production (Norwich) orders, plus injunctions in franchise disputes.
Fraud
Civil and criminal fraud work covers individuals, organizations, and boards or special committees.
Constitutional and judicial review
The firm's lawyers have acted on constitutional questions in courts at all levels, including the Supreme Court of Canada.
Appeals
Appeals before the Superior Court, the Ontario Court of Appeal and the Supreme Court of Canada are part of the practice.
Crisis management and police and regulatory investigations
Advice reaches law firms, corporate boards and senior management dealing with a crisis. For professionals facing a regulator's misconduct investigation, the firm defends medical, legal and financial professionals.

-
Konstan v. Berkovits, 2024 ONCA 510
Samara Secter and Rebecca Amoah acted for the successful appellant. The Court set aside the trial judge's conclusion that Berkovits was liable for abuse of process, and it spelled out the test for that tort.
