first american president to canada
canada was recognized as a seperate nation on july 1 1867, warren g harding (of ohio-my suprise there in seeing he was the first) was the first american president to visit canada, in vancouver april 26, 1923. now since harding grew up in ohio, and since we get lots of cold weather here off to find out if he saw/played/watched hockey.....
*ETA* the date was the first official visit by an american president i could find. teddy roosevelt likely traveled there given his love of adventure, just not as the american president. and harding high school in marion ohio has a very good hockey team
