Our core services include:

  • Data Breach – Prevention, Response and Mitigation: We serve as advisors for clients to prevent, respond and mitigate the consequences of data security incidents. Our lawyers work closely with forensic experts, regulators and law enforcement to contain and manage breaches, communicate with threat actors, mitigate reputational and legal risks, and ensure timely and compliant notifications. We help clients proactively prepare through privacy and data security impact assessments, audits and incident response planning.
  • M&A Reviews and Risk Assessments: Our team assesses strengths, weaknesses and risks associated with business transactions. We conduct privacy and cybersecurity due diligence during mergers, acquisitions and other corporate transactions. We identify data-related liabilities, assess compliance with Canadian and international privacy laws, and negotiate transaction agreements to mitigate and properly allocate risks.
  • Data Processing and Other Commercial Agreements: We draft and negotiate data protection provisions in commercial contracts where privacy and data security are meaningful elements. This includes various types of commercial agreements, including outsourcing, hosting and SaaS arrangements, and data processing, data sharing and license agreements. Our lawyers ensure these agreements reflect evolving industry and legal standards and address cross-border data transfers, breach notification protocols and confidentiality obligations.
  • Privacy and Data Breach Litigation and Class Action: We represent business-side clients in privacy and data security-related litigation, including class actions stemming from data breaches or alleged misuse of personal and confidential information. Our litigation team defends against claims of negligence, breach of contract, unauthorized processing of information and regulatory non-compliance, while managing reputational and financial exposure.
  • Freedom of Information and Access to Information: We advise clients on compliance with federal and provincial freedom of information and access to information laws, including the Access to Information Act and its provincial and territorial counterparts. Our services include responding to access requests, applying exemptions and representing clients in mediation, arbitration and appeals through the courts.
  • Privacy and Insolvency: In insolvency and restructuring matters, we guide clients on the treatment of personal data and confidential information held by distressed entities. We ensure that data transfers, sales or disclosures comply with privacy legislation and security requirements, and balance the interests of creditors, purchasers and affected individuals.
  • National Security Considerations: We guide clients through Canada’s national security laws as they intersect with privacy and data protection, advising on compliance, data localization, breach reporting and risk management. Our team also supports sensitive transactions and investigations that may trigger regulatory scrutiny or disclosure obligations.
