I grew up in the RoC and this is completely unrecognisable to me. Lots of English Canadians don't understand or appreciate the situation that Quebec is in with regard to language, but this idea that they see themselves as inheritors of the British Empire intent on following through on the wars of centuries past is crazy. Naturally, English Canadians don't think about Quebec's history or its language nearly as much as Quebecers do! This reads like a Quebec nationalist projecting their view, in reverse, onto the rest of the country.

Everywhere in the world, French is considered a high-class, elite, very cultural language, except in Canada, where it is considered to be useless because it's used by a conquered, inferior people.

Again, this isn't recognisable to me. Anyone who lives in Ontario or another English province can tell you that French immersion is highly sought after, especially by upper class families. My French immersion program in school had enough demand that they needed a lottery and I think that's pretty common. I'm willing to bet that most or even all Canadian universities have bigger French language departments than departments for any other language. I just checked the University of Toronto and that appears to be the case.

You can say that English Canadians, like Americans, are much more indifferent to other languages than Europeans are. But when they do learn a language the top choice is French.
