Addario Law Group LLP: one of the best criminal law firms in Canada.

Frank Addario leads a group of smart, hard-working advocates committed to finding innovative ways to help clients solve their criminal, regulatory and constitutional law problems. Our goal is to guide clients safely through complex legal situations. From investigation to charging decision to trial, we work hard to protect clients from disruption to their life, business and reputation.




We defend individuals and organizations accused of criminal and regulatory offences.  Our lawyers have experience defending a wide variety of criminal and regulatory charges, including the most serious offences. We bring this experience to bear every time we step into the courtroom or negotiate with prosecutors.  We are diligent, creative and effective. Finding innovative ways to defend our clients’ interests is what we do best.

We are results-oriented and always remain focused on achieving the best possible solution for our client. Our lawyers bring a constructive approach to the courts and our adversaries. We spend most of our working days in court where we have established our reputation with colleagues, adversaries and judges.


We are often brought in by general counsel to assist 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.



We work with general counsel and outside corporate counsel to contain and solve our clients’ internal legal problems. Our lawyers provide reliable advice discreetly and quickly to Boards, senior management and audit committees in the course of crisis management. We represent banks, manufacturers, law firms and other large organizations with internal challenges that may attract external scrutiny.


We have experience representing clients at all levels of Court in Ontario. We regularly prepare and argue appeals in criminal and constitutional cases before the Superior Court, the Ontario Court of Appeal and the Supreme Court of Canada.

Our team of lawyers includes former clerks from every level of appeal court in 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 bear in every appeal we argue and have successfully advanced appeals from conviction in many factually and legally complex cases.


We provide advice and legal opinions to individuals, corporations and organizations about their legal rights and responsibilities. Our goal is to quickly and efficiently answer legal questions efficiently and in plain language. We regularly provide advice to major online businesses about compliance with criminal and quasi-criminal reporting obligations and responding to police investigations.
