Cassandra has extensive experience in civil litigation across a broad range of practice areas and industries. She is pragmatic and focuses on practical solutions to her clients’ needs.

Cassandra has represented clients at all levels of Court in Alberta, including as lead counsel for trial at the Court of King’s Bench and the Court of Appeal. She has been involved in several injunctive matters, obtaining rare and extraordinary relief granted by the Court in emergency circumstances. She has also represented clients before administrative bodies from the initial complaint and investigation, through to tribunal appeals and judicial review.

Cassandra has been involved in large‑scale, complex commercial litigation and arbitrations. Such work has included an arbitral dispute wherein an $80‑million arbitration award was granted in favour of the client, and an oil & gas arbitration involving complex issues of contract interpretation. She was also part of team representing an international energy company in a dispute regarding a right of first refusal clause in a complex matrix of oil and gas agreements. This matter involved pursuing relief in respect of a billion‑dollar oil sands transaction.

Cassandra has been involved in a number of high‑profile matters. Most notably, she served as co‑counsel in a class action arising from the sexual exploitation and assault of numerous class members over a period spanning nearly 24 years. The action addressed three decades of luring, grooming, sexual assaults, and sexual abuse by a volunteer and employee of the defendants. The affected class members were students of, and performers with, The Young Canadians, a prestigious performing arts facility operated by the Stampede Defendants. This case received extensive local and national press coverage.

Class counsel is in the process of finalizing the administrative items pursuant to the approved settlement and expects that to be completed by April of 2026.

  • Plastk Financial & Rewards Inc. v Digital Commerce Bank, 2023 ABKB 458. Cassandra represented Digital Commerce Bank, a Schedule 1 Canadian chartered bank which provided payment and banking solutions to the Plaintiff. In this application, the Plaintiff’s interim relief was vacated, and a freezing order/mareva injunction was obtained against the Plaintiff and other parties after discovery of alleged large‑scale fraud. Summary judgment was obtained on the fraud allegations, together with an order requiring the Plaintiff to post security for costs before taking further steps in the action.

An Attachment Order was obtained restraining Folium Canada from transferring property worth in excess of $5M. Cassandra also assisted in enforcing the judgment through a forced sale of the Defendant’s land, resulting in the judgment being paid in full in February 2025.
