But then it wouldn't have been an Emmerich film... what you are describing sounds more like a philosophical evaluation of the world and its institutions and how they would react to extreme stress. Emmerich wouldn't direct that, because there wouldn't be many special effects involved in evoking the destruction of the world economy and the collapse of American infrastructure.
Besides, not many people would go to see a movie like that... let's face it: people like the cool tidal waves, macro-hurricanes, and Ian Holm delivering lines like "Oh, I'm afraid it's too late for that." People like it when a father trudges through a blizzard to get to his son, who for all he knows, will be dead if and when he ever gets to him. Because they like the cool snow effects. Who could resist a picture of the Statue of Liberty, frozen, protruding only a hundred feet above the barren white landscape which used to be NY harbor? Yes, the plot left something to be desired, and I could not understand much of what the main characters did and why, but oddly enough, I liked the film.
And in answer to your question, the Canadians would be extinct. They would win no more ice skating medals at the Olympics. But, hell, neither would Russia--they'd be extinct too. Talk about a disaster: Mexico sweeping the medals at the Winter Olympics.
