Services

  • PRE-CHARGE ADVOCACY & CRIMINAL TRIALS

    We specialize in pre-charge advocacy for individuals and organizations to prevent enforcement action, penalties or charges. This work requires energy, judgment and an excellent working relationship with enforcement and prosecution agencies. Our most successful advocacy is known only to those most affected: if you have never heard of our work in this area, we succeeded.


    If the authorities lay charges, our lawyers defend a wide variety of criminal and regulatory matters, from administrative decisions to the most serious offences. Our signatures are creativity, preparation, and nimble responses to evolving problems. We bring our reputation with adversaries and judges to each client’s case.

  • POLICE & REGULATORY INVESTIGATIONS

    General counsel seek our assistance in separating regulatory and prosecutorial threats from acceptable business risks. We provide strategic advice and direction in responding to investigations to achieve optimum results from containing the problem to defending our client in court. Our legal services include witness interviews, document review, legal and reputational analysis and negotiations with regulators and law enforcement. We help clients who choose to cooperate with external investigations protect their own interests.

  • CRISIS MANAGEMENT

    We provide crisis management advice to law firms and corporate boards, senior management and audit committees. We work with general counsel and outside corporate counsel to contain and solve our clients’ legal problems. We make sure internal challenges don't attract external scrutiny.

  • APPEALS

    We regularly prepare and argue appeals in criminal and constitutional cases at the Superior Court, the Ontario Court of Appeal and the Supreme Court of Canada. Effective appellate advocacy requires a combination of intellectual rigour, practical advocacy skills and an ability to view legal problems creatively. We bring these skills to every appeal we argue and have successfully advanced appeals in many factually and legally complex cases.


    Our team of lawyers includes former clerks from every level of appeal court in Canada.
