I have often wondered in the Confederation of States people ever got their way, would they re-introduce slavery? This movement could be a mask for racist tendencies.
Anyways, Canada has its own English/French divide that goes back to 1759, when the British governor had a need to conquer the French colony.
The acquisition of Quebec was always troublesome for the British. When Upper Canada (now Ontario) staged a rebellion or two, the British realized that they need to cut their losses. They gave Canada its independence in 1867. Because this was done peacefully, they made sure there were a lot of connections between Canada and the UK. Upper Canada already had its Westminster-style parliament (albeit with London having a veto), Canada just continued with that system of governance. Depending on the historian, Canada was not fully independent until WW1 or WW2. Even today, the Queen of English has a veto over the Canadian Parliament.
