In Re Walter Energy Canada Holdings, Inc, 2017 BCSC 709 (available here) the British Columbia Supreme Court had to consider the validity of a large claim (over $1 billion) filed in restructuring proceedings underway in the province under federal legislation. The claim was for unfunded pension liabilities and was based on an American statute, the Employee Retirement and Income Security Act of 1974, 29 U.S.C. § 1001. So the court had to consider whether that statute could apply to a claim in British Columbia against entities organized in Canada (mostly in British Columbia).
In Endean v British Columbia, 2016 SCC 42 (available here) the Supreme Court of Canada has held that “In pan-national class action proceedings over which the superior court has subject-matter and personal jurisdiction, a judge of that court has the discretion to hold a hearing outside his or her territory in conjunction with other judges managing related class actions, provided that the judge will not have to resort to the court’s coercive powers in order to convene or conduct the hearing and the hearing is not contrary to the law of the place in which it will be held” (quotation from the court’s summary/headnote).
