@Mame,
Here's a thumbnail sketch of how most of Canada became Anglicized (with the notable exception of Quebec). As you suggest, Mame, Set could do a far better job of it, but he ain't here so you'll just have to put up with my faulty memory.
Until the conflict which in the US is known as the French and Indian Wars (think
Last of the Mohicans) or in the UK as Queen Anne's War, any place that was known as Canada or a part of Canada was a colony of France. This was territory that was a hell of a lot bigger than present-day Canada. It included large parts of what today is the US Midwest. Most of what later came to be known as the Louisiana Purchase was, in the early days, a part of Canada. There are still places in Oklahoma and elsewhere that have the name of Canada in them: Canada Creek, Canadian River etc.
When the French and the English went to war in Europe, the British Colonists in New England took part by attacking French possessions in North America. A very young George Washington made his reputation here by capturing Fort Duquesne (site of present-day Pittsburgh, PA. The final outcome of that war was in favor of the English. As part of the spoils, they took possession of all the Eastern Colonies that France had (essentially present-day Quebec, parts of Ontario, parts of the Maritime provinces). The Francophone Quebecois were given a very limited amount of autonomy, mainly in that His Royal Majesty in London and his minions were willing to accept the fact that these people did not, and would not, speak the King's English. There was trouble from the git-go and it has not abated over the centuries.
Many Quebecois have never given up hope that at some time in the future they might become an independent country. Economically, that would be suicidal. The statistics clearly show that more Canadian Federal tax dollars go to shore up Quebec than go to any other province. Self-supporting they're not. But many feel little or no connection to the Anglophone majority and the dream lives on.
If there are any egregious errors of fact in the above thumbnail sketch, I'm sure I'll stand corrected (and properly excoriated).
