No, Richard, you were the one who referred to these lesser offences as 'misdemeanours': I merely pointed out that it's criminal law terminology.

Ghomeshi wasn't acquitted because the allegations were minor - as the excerpt I quoted showed.

But sure, they could broaden Human Rights Codes to bring more minor sexual transgressions into them and out of the Criminal Code.  That would mean (a) no prison time, (b) 'prosecution' by individuals, not by the state, and (c) decisions on a balance of probabilities, not beyond a reasonable doubt.
