Our criminal code defines defamatory libel as a matter published that is likely to injure the reputation of a person by exposing him/her to hatred, …contempt or ridicule or designed to insult the person. A libel is published when it is exhibited in public or caused to be read or seen. If convicted of this you can go to jail for 2 years even if the libel is true. Be very careful what you say on social media because in Canada you can go to jail for speaking the truth.
