Yup, fairly common comment amongst Canadian historians that 1812 was the Canadian War of Independance. Without it they would have been happy to join the US eventually or have Quebec go its own way or what have you.
That's borne out by the second verse of what was once (and IMO should still be) the Canadian national anthem,
The Maple Leaf Forever:
At Queenston Heights and Lundy's Lane
Our brave fathers side by side
For freedom's home and loved ones dear,
Firmly stood and nobly died.
And so their rights which they maintained,
We swear to yield them never.
Our watchword ever more shall be
The Maple Leaf Forever
It should be noted that Queenston Heights and Lundy's Lane are both locations very near the Niagara frontier.
I was under the impression that most historians would call that war a draw, since (particularly) the terms of the Treaty of Ghent could be summed up as
status quo ante bellum; i.e., things as they were before the war. Granted, the US got a few concessions on issues such as impressment but by then the points were largely moot.
It seems to me that had the war not been fought--and it almost wasn't--it's entirely possible that Canada might not exist as a nation today, or would be one that occupied the northeastern part of the continent: that is to say, the present-day Maritimes, Quebec and Ontario, and possibly eastern/northern Manitoba, along with some fraction of what was once called the Northwest Territories.
I have to admit that as an American with a
very strong affinity for Canada (it's possible I'm one of the very few Yanks who can name more than one Canadian prime minister from the past), I find it a tad uncomfortable that we were once the enemy--just as, I'm sure, the British are a bit uncomfortable with some references to "the foe's haughty host"--meaning them--in the latter verses of
The Star-Spangled Banner.
