They're taking a fully US-centric approach, treating abortion as a political topic - see https://business.twitter.com/en/help/ads-policies/restricted... . You can't advocate for abortion in Canadian ads. Which is insane, considering abortion is fully legal here. Going down that list, it's "things that are controversial in America".

Not really. Canada prohibits hate speech and discrimination against LGBTQ people. The whole "using the wrong pronouns is now a criminal offense" meme was made up by someone looking for something to be offended about/sell books about how PC culture is ruining everything.[1]
People can be sued for discriminating on the basis of gender identity or expression. Repeatedly using the wrong pronoun can be used as evidence of that, but probably has to fit into a larger pattern of behavior. And that's the kind of thing you could credibly sue an employer or business for in the US as well.

Also, doesn't Canada have a few laws on the books regarding how people are allowed to address other people, specifically, LGBTQ people?
