From a FreeD account of some pre-trial stuff in Levant v. Warman:
Mr. S[c]hiller said that Ezra [Levant] is on a "campaign against the Human Rights Commissions". He said that Ezra is entitled to do that, but he is not entitled to make false statements. Shiller said that he has three other clients with cases against Ezra and, surprisingly, said that he has another one coming up.
