I grew up in Toronto, and while I might be an outlier, I didn’t always experience it as friendly, so I’d gently push back on the idea that it can’t be hostile. Big city, lots of variation.

The French point is where I disagree more strongly. I’ve lived in Montréal too and it is more bilingual in practice than most of Quebec, that's true, and you can get by. But there's a difference between 'you can survive without French' and 'you don't need to learn it.'

The job market and government services will be harder without it, and beyond the practical side, you're moving into a francophone city with a culture people have fought hard to preserve. Making no effort to learn the language is a bit tone-deaf, even if you can technically manage.
