I deduced on the trip to and from that 1) Canada must have gotten a REALLY big quantity discount on big blue and white signs that say "Ontario" on 2/3 of the surface area, leaving the other 1/3 to tell you something important in really small font and 2) the really small font was simply used to annoy BobKay if he spends 12-14 hours driving each way on a trip to Canada.
