Scots, of whom many Canadians are ancestors, spell it “whisky.” All non-Scotch uh whisky is spelled “whiskey.”
While I wasn't specifically aware of that I'm not surprised.Of course there are a number of words that we Yanks spell,and pronounce,differently than do subjects of the Queen...and I've just learned of the existence of another one.
But I absolutely draw the line at haggis! ;-)
