Canada’s federal structure means national class actions naturally raise potential constitutional questions. Those questions become potentially more thorny where a class action is pursued not on behalf of individuals across multiple provinces and territories, but instead provincial and territorial governments themselves. The Supreme Court’s recent decision in Sanis Health Inc v British Columbia addressed many of those concerns and ultimately defined a broad scope for national class proceedings, including where a proposed class includes other provincial or territorial governments.

As widely reported by the likes of CBC, the Guardian, the Verge and CNBC, OpenAI has indicated they will “pause” the use of their AI-generated voice after users (and Scarlett Johansson herself) noted the striking similarity to Scarlett Johansson's voice from the film “Her”. This connection may have been intentional, OpenAI’s CEO, Sam Altman, posted a one-word message – “her” – on his social media on the day the AI-generated voice was unveiled.

Bars or Bytes? Exploring the Implications of a Track that Drake Might (or Might Not) Have Created
Did Drake respond to an alleged feud with fellow artists, including Kendrick Lamar and Rick Ross? As reported by the LA Times, a track titled ‘Push Ups (Drop and Give Me 50)’ appeared online recently, taking aim at Lamar and several of his recent musical collaborators. However, this track remained unclaimed on any of Drake’s official platforms, causing some to question whether this track was fan-generated using artificial intelligence. This cynicism may be justified: Drake is reportedly no stranger to having to denounce fan-generated songs, and Lamar’s rumoured response was actually the work of artificial intelligence and another rapper.

Class Actions: Settling at the court’s discretion
Parties to class action settlements often settle, at least in part, to avoid the ordinary uncertainty of litigation. Courts have long emphasized that while they retain discretion to supervise payments of lawyers’ fees as part of a settlement, the settlement approval process will not entail the Court re-writing a settlement that it is not prepared to approve.
