Oppression Claims/Securities/Shareholders Disputes
In Telus Corp. v. Mason Capital Management LLC, the firm represented Mason Capital, an American hedge fund, in a corporate battle against Telus.

Lexpert Magazine has referred to this case as “an epic shareholder dispute that demanded inter-firm teamwork and strategic vision.”
The firm has successfully represented parties in two of Canada’s most significant mining cases: Minera Aquiline Argentina SA v. IMA Explorations Inc. and Inmet Mining Corp. v. Homestake Canada Inc.
In Minera Aquiline, the defendant was compelled to transfer to the plaintiff the Navidad Project – a world class silver deposit in Argentina – as a result of its unlawful use of confidential exploration data.
In Inmet, the plaintiff vendor of a gold mine was awarded $111 million from the defendant who unlawfully refused to complete a purchase agreement on the basis of an alleged failure to disclose material facts.

The plaintiff, a former client of the law firm, accused the law firm and one of its former partners of breach of fiduciary duty resulting from acting in a conflict of interest. While the plaintiff achieved some success in the Court of Appeal, in the Supreme Court of Canada the law firm was exonerated of misconduct and the remedy awarded by the Court of Appeal was substantially reduced.
In Hollinger Inc. v. Radler, the firm successfully defended an application to continue an ex parte mareva injunction pronounced by the Supreme Court of British Columbia on October 25, 2006.
