The strongest argument I have is what is actually in the guide itself:

It's pretty clear to me. You definitely have to use their preferred pronoun, and as for "xe" and "xir", the OHRC have gone "eh, we're not sure yet, we'll decide later, but if you go ahead and refuse to use their pronoun we just might penalise you. So you should probably use those too."

Not surprising that lawyers advised the university he was in breach, is it?

(I acknowledge you think the paragraph following it is saying you can call them by their name if you don't want to use their pronoun, but I think it's quite clear that paragraph refers to using their name if you can't tell what gender-neutral pronoun they want you to use, which wouldn't contradict what I've quoted, whereas your interpretation does)

Lucky for everyone, the vast majority of the world know what the word "always" means. Any, let's move on from that point. We obviously aren't going to change each other's minds there.

Ok, now I get the point you were making previously, I think. No, that's not how this works. The law isn't extending protections to trans people, it's extending protections to "gender expression" and "gender identity". I.e., everyone's gender expression and gender identity. But not every facet of a person's identity; just gender.

There's nothing in the law about "racial identity" or "national identity" or "religious identity" is there? But there is gender identity. It's the only protection that is specifically "identity". Whilst deliberately leaving what that means open-ended, and referencing the OHRC which specifically talks about pronouns as part of gender identity, whilst saying "you gotta call them he or she if they tell you to, and as for xe and xir, maybe use those too or we just might come after you, buddy".

We won't know whether refusal to use a preferred pronoun will constitute a violation of a person's human rights in Canada until such a case comes before a judge. That's the reality of this. But in the meantime, it follows perfectly clearly to see how that is a real possibility.

Notably, it says "creed" and leaves that open to interpretation. Believing you are a Christian is part of your creed. But we're getting somewhere, I like this. You'd be fine if it just said gender expression then? Or transgender status? Or what word would you use instead?
