Overview

Justin Lambert maintains a complex commercial litigation practice focusing on securities litigation, fraud recovery and energy disputes. A practical litigator, he works to align litigation with his clients’ broader strategic and business objectives.

Justin is frequently called upon to handle intricate securities litigation matters including shareholder disputes, oppression claims, directors’ duties, corporate mergers, proxy solicitations and regulatory issues.

He also assists corporations and special committees in conducting internal investigations into whistleblower complaints. His experience includes investigating allegations such as insider trading, foreign corrupt practices, vendor kickbacks and misstatements in publicly released audited financial statements. These matters often require coordination with auditors, domestic regulators and cross-border collaboration with colleagues in other jurisdictions.

Justin helps clients trace, freeze and recover fraudulently misappropriated funds using various legal tools and court orders including court-appointed receivers. He has extensive experience tracing and recovering assets across provincial and international borders.

His energy litigation practice includes disputes over royalties, leases and ownership of interests in wells. He also assists clients in resolving conflicts related to industry-standard form operating agreements, leases and accounting procedures.

Beyond these areas, Justin advises clients on a wide range of commercial litigation matters. He has appeared before all levels of court in Alberta and has experience in both domestic and international arbitration.

Justin is also a founding board member of Brady’s Foundation for Pediatric Palliative Care, a charitable organization that provides financial and other assistance to families of children with rare life-limiting diseases and genetic conditions.
