USA (37)
There is no "winning country" in the Olympics. The games celebrate human achievement not national achievement. That being said, the US has won the most medals overall in all of the Olympics, Canada may well have won the most Gold Medals in a Winter Olympics and the US may well have won the most medals of any type in any of the Winter Olympics. I don't know which country has won the most Golds and most medals overall in the Summer Olympics.
U.S.A. The United States has won the most overall medals. More specifically, the gold, silver, and bronze medals in the summer and winter games combined. However, Norway has outperformed the United States in the winter Olympics overall.
There were no Winter Olympics in 1996.
Canada won most gold medals (14) overall in the 2010 Winter Olympics in Vancouver.
The previous record for gold medals by the host country was 10. The previous best for gold medals at the winter games, host or not, was 13 by Norway and Russia.
