[post-it]

I think it is an American vs Canadian thing. The list of ten largest banks in North America is nearly evenly split between American and Canadian banks[0], so the five main Canadian banks are 10x as large as their American counterparts, proportional to the population.

The only conceivable scenario where a major Canadian bank fails and any depositors are not made whole is one where the government has lost the ability to maintain the currency and the Canadian dollar is worthless anyway.
