Based in my rough and not statistically based sample it appears that there are fewer snowboarders in Canada, at least at Mount St. Anne in Quebec. It appears that there are about 25-30 percent fewer than I am used to in the Northeastern United States.
The second thing I noticed is what I call the Canadian Style. Canadians by in large ski much more like racers than those in the Northeastern US resorts. They carve their turns much more, getting lower which each turn and getting “on edge”. See this video:
Nice people though. Don’t let the language barrier, or the perceived language barrier, intimidate you.
