Smokin' Joe observes:
"I reckon it's time for Alberta and Saskatchewan to secede."
... Along with Manitoba, the Yukon and Northwest Territories, also.
I predict that Canada may indeed break up in the future, but... not until there's "a separation" in these [formerly] United States as well.
If that occurs -- if The Heartland breaks away -- I sense that it will be a signal to the Quebec'ers that the time has come for them to make their move. Would Canada fight a civil war amongst itself? With what army (they have almost none)?
We might see the Maritimes form their own nation -- perhaps drawing in some of New England. British Columbia (leftist) would make a good fit with western Washington and Oregon. Ontario -- isolated by itself -- might "look southward" to Minnesota, some of Wisconsin, Northern Illinois (i.e. shi*cago), perhaps even Michigan.
Uncertain times ahead.
But ... you know that it's coming.
What will cause "the fission" ...?
