The amount of gold medals counts because you could have one country the didn't win anything, but has a bunch of bronze medals at the top of the chart and that doesn't make any sense... AFAIK USA is the only country that counts total medals for placement.
Technically, Canada was in the top spot for medal count in Vancouver, because Canada had the most amount of gold medals.
During the Vancouver games, I saw both methods listed by different Canadian sources. Don't remember the actual sources, but, for example, the Toronto Star may have used the total medals method, meaning the US "won", but the Vancouver Sun used the most gold method, giving Canada the win.
100% of European sources used the gold standard, while 100% of US sources used total medals. A few less credible US sites occasionally try the points method: i.e., 5 point for gold, 3 for silver, 1 for bronze.....or 3,2,1...or something similar. One site was using this throughout the Bejing games in 2008, then abandoned it when China started "beating" the US due to China's higher gold medal count.
In any event, at the end of competition on Monday, Canada is winning by any method.
(Unless you want to believe some Quebec separatist sources, which lists Quebec with 5 medals and Canada with 2.)
