I was raised in Ontario, Canada. I now live in the USA.
I too was required to learn French, starting in grade 7. I wish I had started earlier. And we began with Parisian French, not Canadian French, the latter showing up in later years. Since those days, French immersion schools have appeared, offering instruction predominantly but not exclusively in French. I think my French fluency would have been much better if I had attended such a school. I have many younger family-members who attended these schools. It helped them tremendously, and it certainly didn't diminish their fluency in English.
I'm puzzled and amused at your derision of "Canadianized" French, while at the same time defending the Canadian dialect of English. They both are worthy of respect and preservation. Francophones in Canada would take exception to your claim that their language and culture are "dying." And I see it as only a Good Thing for English-speaking Canadians to learn at least a little French in order to get a better understanding of 25% of the people living in the country. That is not a "ridiculously small" part of the country's population.
There was a time long ago when the standard for a language was determined by the way the sovereign of the region spoke. Nowadays, I would say the media has taken over that role. And you certainly could do worse than speak the kind of French spoken on Radio Canada (the French wing of the Canadian Broadcasting Corporation.) I would describe it as français international -- not "Canadianized" French. French-speakers from pretty much anywhere in the world could understand it without much trouble, just as most English speakers can understand English broadcasts from a variety of countries. And the reverse holds: those who learn French in Canada can adjust to French spoken elsewhere in the world with minimal effort. It's misguided to call it a language that "0%" of the world uses.
And as for your claim of "forced adoption" -- I think Baron_Yam below has it right. It's not about forced adoption, it's about protection from a flood of US content that could overwhelm and destroy Canadian culture. We're all free to watch or listen to whatever we want (and good for you, for listening to Canadian bands) but if Canadian content isn't protected, promoted, and preserved, then it could be lost in the sheer magnitude of stuff coming from south of the border.
