Can't speak for anyone and wouldn't try, whether Canadian or American, but I'd wager 5 figures ANY time you like that the U.S. would absolutely welcome Alberta and Saskatchewan as states, merely by their request.
I'll make you a second wager, too: if Martin insists on compensation, the U.S. will cheerfully give up Maine, at least. Might throw in another state, too, say VT or MA -- but contiguity MIGHT be a problem, wouldn't it? (w!)
You can keep the Maritimes; the U.S. doesn't need and likely wouldn't accept as an add-on a generally white version of Gary, IN or Washington, DC.
Perhaps that little swine Martin might have to accept a draft choice to be named later.
DO have a nice day, won't you?
