I haven't heard as much about C-63 as I have about S-210 the "show your id to watch porn act".
Part of C-63 amends the criminal code so that hate speech is defined relative to the charter's prohibited grounds of discrimination.
The prohibited grounds are interesting because although they started as a defined list in the charter, the charter leaves it to the courts to add to the list. Which they have done with sexual orientation, gender expression, genetic characteristics and others.
