  • David Stevens v. Ithaca Energy Limited et al. Acted for the parties in a securities class action involving alleged market misrepresentations in both core and non-core disclosure documents. The claim arose from a significant decline in Ithaca Energy’s share price following market disclosures regarding delays in the refurbishment and deployment of a floating production facility in the North Sea. The action alleged that shareholders suffered losses as a result of these misrepresentations. The matter was successfully resolved with a court-approved settlement totaling $9 million.

  • ATCO Electric and others v Alberta Utilities Commission. Alberta Utilities Commission Proceeding 29006; Court of Appeal Action no. 2501-0235AC. Counsel to FortisAlberta, in a Court of Appeal of Alberta directed examination of distribution facility owner payments under the Independent System Operator tariff customer contribution policy. This case relates to the payment of contributions in aid of construction (“CIAC”) paid pursuant to a customer contribution policy established by the AESO under the Electric Utilities Act. Our firm represented FortisAlberta in the Alberta Utilities Commission’s hearing regarding the Independent System Operator tariff customer contribution policy. FortisAlberta was the primary utility respondent in the examination. The potential amounts in issue are in the hundreds of millions of dollars. In particular, the Alberta Utilities Commission decision addressed whether the AESO is permitted to establish a policy that required distribution facility owners to pay CIAC in relation to transmission facility construction or upgrades, whether the AUC is compelled by legislation to require transmission facility owners to pay or repay CIAC, to include these amounts in their capital base or to earn a return on those expenditures. ATCO, AltaLink, ENMAX and EPCOR have appealed.

  • JL Energy Transportation Inc v Alliance Pipeline Limited Partnership. Represented the parties in a high-value intellectual property dispute concerning the alleged misuse of licensed and patented natural gas transmission technology. The case, with claims exceeding CAD 100 million, is now a leading Alberta (and potentially Canadian) authority on the interplay between provincial limitation periods and the federal Patent Act. In 2025, the Alberta Court of Appeal (2025 ABCA 26) clarified that the federal Patent Act limitation period applies, reversing its earlier decision in Canadian Energy Services Inc v Secure Energy Services Inc (2022 ABCA 200).
