The complex regional and cultural composition of Canadian society means that there is no single Canadian way of life, but certain generalizations can be made. Perhaps the clearest is that Canada shares with the United States, most European countries, and Japan a high standard of living relative to the remainder of the world. Most Canadians are well housed, fed, and clothed. Canadians also enjoy an advanced, efficient health care system that is universally available to all citizens and landed immigrants irrespective of their location, income, or social standing. In fact, recent opinion polls have shown that Canadians see this system of socialized medicine as a defining characteristic of their national identity.
