That's because you allow US media to influence your knowledge of Canadian law. It's something that is rampant in Canadian culture.

Unfortunately though, you're wrong again. It is not simply just inciting violence or saying obscene things. It applies to willful promotion of hatred towards an identifable group.

Section 319(2) makes it an offence to wilfully promote hatred against any identifiable group, by making statements (other than in private conversation). The Crown prosecutor can proceed either by indictment or by summary process. The maximum penalty is imprisonment of not more than two years.

I even provided the wiki for you to read. Clearly you did not.

Also, seeing as you've never heard it called that would imply you've never read about your rights in Canada. It is called that to protect it from the stupidness that occurs in the US where people just bark craziness and then claim freedom of speech.
