Businesses face increasingly complex and often overlapping regulation, and corresponding enforcement efforts from government authorities.
Osler’s Government Investigations and White-Collar Defence Group has the insight and experience to help clients navigate the evolving enforcement landscape, address investigations and allegations regarding wrongdoings, and mitigate associated risks that can have financial, operational and reputational impacts on your organization, its leaders and stakeholders.
Our integrated team regularly advises and represents corporations, senior executives, board members and public officials in a wide range of domestic (federal, provincial and municipal) and cross-border investigations and regulatory enforcement matters. These include allegations of capital markets abuses such as insider trading and market manipulation, foreign and domestic corruption, money laundering, sanctions violations and fraud, as well as anti-competitive conduct, tax evasion, and environmental wrongdoing.
In addition to responding to actual, threatened or potential government action, our group proactively conducts sensitive internal investigations for leading companies in almost every business sector, and advises clients in matters involving financial, regulatory and reputational risks. We represent clients in Canadian courts, before regulatory tribunals and in associated appellate proceedings. We also regularly act in a wide range of cross-border matters involving foreign regulators and law enforcement agencies, including the U.S. Securities and Exchange Commission, the Office of Foreign Asset Control, the Federal Bureau of Investigation and the U.S. Department of Justice, as well as in the United Kingdom and Europe.
Our Government Investigations and White-Collar Defence team coordinates and works in collaboration with other members of our multidisciplinary Risk Management and Crisis Response team to most effectively address the risks facing your organization, its leaders and its stakeholders.
