It will be a busy new year for General Motors of Canada’s legal team. The appeal of an almost $1 billion class action claim against the company is scheduled to be heard in the Ontario Court of Appeal this January, in what Kent Thomson of Davies Ward Phillips and Vineberg calls “the definition of high-stakes litigation.”

Thomson, who’s acted for GM in this matter since 2014, told The American Lawyer he couldn’t “think of a bigger, more high-stakes class action that’s reached trial, certainly in this country.”
