Perhaps but how do you have a trial with this many thousands of individuals at the same time, who all have a right to be heard! In reality, you don't. Any sane judge would order the plaintiffs to turn it into a class action or forget about it. And I'm quite sure that thousands of "doctors' notes" would be rewarded with heavy sanctions. Wasting the legal system's time is not a constitutional right. And aren't you Canadian, anyway?
