We had twin rebellions in 1837-8 that were put down, but we were granted responsible government (that is, self-government) to keep us happy and non-rebellious.
The Treaty of Westminster came about because we felt that, given our sacrifices in WWI, especially at Vimy Ridge, we were a nation and it was about time we were recognised as one.
We didn't get our Constitution until 1982 (the repatriation of the British North America Act - basically it meant the piece of legislation that established the Dominion in 1867 was transferred from the UK to Canada so that we could be in charge of our own Constitution).
Our path to indepence was longer and a bit more sedate than yours, but the demand for change came from this side of the pond.
This is the King-Byng affair I was talking about earlier. I was wrong on a few details.
