If you're looking around the world, yes, there are many different examples, but we start to get into an academic exercise of looking at which country is most similar to Canada. Many countries do have forms of insurance guarantee. Examples include the U.S., the U.K., Germany, and several other countries. Some have preferred status.
The question you want to ask, though, is this: how many of them changed that in the middle? How many of them went from an unsecured to a secured status and did not have an impact on the market? I'm afraid I don't have the answer to that, because this could get into a very large academic exercise.
