What is the test for damages for libellous statements?

With respect to aggravated damages, the test is set forth in Hill v. Church of Scientology of Toronto at paras. 188 and 190: Aggravated damages may be awarded in circumstances where the defendant's conduct has been particularly high-handed or oppressive, thereby increasing the plaintiff's humiliation and anxiety arising from the libellous statement. … If aggravated damages are to be awarded, there must be a finding that the defendant was motivated by actual malice, which increased the injury to the plaintiff, either by spreading further afield the damage to the reputation of the plaintiff, or by increasing the mental distress and humiliation of the plaintiff.
