In this clip with [Jordan Peterson conversing with Russel Brand, Peterson says, (3m:57s)](https://youtu.be/t0ym7XQZ-Hw?t=3m57s)

> The government, for the first time in the history of Canada and really in a move that was unprecedented in English Common Law, under English Common Law, actually mandated the content of voluntary speech.

Did Canada mandate the content of "voluntary speech" in the way Peterson is claiming? Has any other nation under [Common Law](https://en.wikipedia.org/wiki/Common_law) ever mandated the contents of speech in this way?
