Would Keegstra 's behaviour—as replicated by many today—not fall under the Harassing Communications definition?

I lived in Calgary during the time Keegstra was mentioned. Would his behaviour as replicated by many today not fall under the Harassing Communications definition?

Keegstra engaged in Holocaust denial in the classroom which was successfully prosecuted as wilful promotion of hatred. It would currently be addressed, in whole or in part, as wilful promotion of antisemitism through Holocaust denial.
