Well, this is from a friend. Both Japan and certain European countries do not need to be tipped. But if you tip someone in Europe, they might not and probably won't tell you and just pocket it. If you tip someone in Japan, they chase after you and hunt you down to give your money back and possibly apologize.
Canada is the second (or fourth) largest country in the world and 2014 statistics put it's population as being less than both the American state California and the Japanese city Tokyo.
