Break up of Canada? (1890-1920)

Barring something like an U.S. invasion, is there any way that Canada could splinter or fall apart between the years of 1890-1920?
 
A free trade agreement with the US during that time could lead to economic domination by the US and perhaps absorption decades down the line, but nothing immediate.
 
How radical are we talking? Canada's WWI administration was wildly unpopular for pretty sound reasons - I don't think it would take much more to make Quebec rebel at that time, and even a violent change in government/new constitution for the anglophones doesn't seem ASB. But the anglophone provinces have no real problems with each other, so two pieces is as much as it goes, not "splintering".

Wouldn't a "violent change in government" just result in British troops marching in, getting rid of the upstart new government and imposing something similar to what happened with Newfoundland - i.e. a "we're going to take away your self-rule for a few years [in a benevolent sort of way] until you settle down and prove that you can rule yourselves" fashion? That is to say, both forcing the rebellious new government, which could be seen as contravening the law of the Empire and committing High Treason against His Majesty, AND the old government which had proven unpopular to retire into the shadows until a new universally popular government took power, not just puppet rule.
