那種人渣should be punished

You have no evidence that it is 種族歧視. But the child was mal-treated(not allowed to pi-pi). It's a serious behavior(if not crime) in Canada.

The point is that if that FP did the same thing to a white child(or other races), she would lose her job. Why can she can keep her job after she mal-treated a chinese boy? Are chinese so cheap.

It's canada. If our chinese don't fight for our legal right here, no one will care you.
