You have to understand that for the average Canadian, the winter Olympics is a hockey tournament first, a curling tournament second and a bunch of other stuff attached to it third. So on paper these where good Olympics but I doubt that's what the average Canadian is going to take away.
Also worth remembering that if you remove the events added since Sochi we have less golds than in Sochi, and that if you remove the events added since Vancouver we have only 7 gold medals. So in a very real sense our performance is getting worse and being propped up by the events that are being added.
