Canadian Bacon

, a rather twisted comedy loosely based on the war of 1812, but set in modern times

In both instances a bunch of drunken yahoos from the United States of America decide to attack Canada. Difference being that in this movie the drunkards weren't sent packing red faced and brutalised.

The cast, both US and Canada included just about every performer from the Canadian SCTV comedy troupe. Highly featured of course as the ring leader of those drunken louts, was the venerable, and missed John Candy

My understanding of the plot is that some jealousy over sliced ham and tall towers was at the root of this invasion.
