I am not an expert on Canadian constitutional law. To be honest, the Canadian constitution is a tad obtuse and I don’t know if anyone is really an expert in it as it makes little to no sense in lots of ways. Arguably it is second only to the European Union constitution of which I doubt even any of the authors have read it in it’s entirety. But I do recall that in Quebec, unions somehow have a connection to law enforcement such that a violation of a union rule can mean you are served by the actual police force or something to that effect. I suspect a closer examination of the relationship in Quebec law between unions and the state would explain a lot of what is seen in this video.
