What we do

A robust criminal litigation practice is at our firm’s core. We defend against all types of criminal charges before every level of court across Canada. No charge is too big, or too small. Our lawyers have experience dealing with a wide variety of criminal offences, including white collar and financial crimes, homicide, sexual assault, drug offences, and impaired and dangerous driving.

Our lawyers can assist with bail, Charter applications, and other constitutional litigation. We are a team of dedicated advocates who work tirelessly on behalf of our clients’ interests.

GHW has a long history arguing criminal and regulatory appeals. Our lawyers regularly appear before appellate courts across the country and on behalf of appellants, respondents, and interveners at the Supreme Court of Canada. We bring decades of experience, a reputation for excellent advocacy, and a deep understanding of the law to our appellate practice.
Our firm has extensive experience assisting professionals facing disciplinary action. We routinely assist lawyers, physicians, and other regulated professionals in navigating their respective regulatory process, including responding to complaints and inquiries during the investigative stage, and defending allegations of professional misconduct before tribunals. We also provide legal advice to professionals before, during, and after complaints and investigations, including on standards of practice, billing issues, and compliance with governing regulations and rules of professional conduct.

Our lawyers frequently advise individuals and corporations facing non-criminal, regulatory issues, including Ontario Securities Commission investigations and charges, Competition Act offences, Elections Act allegations, all Provincial Offences Act charges, as well as investigations and charges under the Occupational Health and Safety and Environmental Protection Acts.

Our firm has significant experience responding to MLAT requests and representing clients facing extradition from Canada to other countries and providing advice to colleagues abroad whose clients are subject to extradition to Canada. We have been counsel on many of the leading cases in these areas. We are frequently consulted both domestically and internationally by individuals and organizations seeking advice about their legal rights and potential jeopardy.
We provide timely, practical, and insightful legal advice and guidance to individuals and corporations on a broad variety of topics. Whether you require assistance dealing with a crisis, are under police investigation, have been called to testify as a witness at an inquest or trial, require assistance retaining counsel in another jurisdiction, are a complainant in a criminal matter, or just need assistance navigating the legal system, we can help.
Our firm has experience dealing with all aspects of criminal and civil asset forfeiture. Often, an application for forfeiture of money or property is brought by the Crown following a criminal proceeding. Sometimes, the state independently seeks forfeiture, even when there has been no criminal charge. We have effectively advocated on behalf of clients whose property has been the subject of both types of forfeiture applications and can assist in providing legal advice and litigation support to individuals or corporations on these issues.
