Been thinking about this for years.
It's easy to think that any % > 0 is a sign of something having gone wrong. My default guess used to be that, too.
But imagine a perfect health system: when all other causes of death are removed, what else remains?
If by "terrible inadequacies of Canadian health care" you mean they've not yet solved aging, not yet cured all diseases, and not yet developed instant-response life-saving kits for all accidents up to and including total body disruption, then yes, any less than 100% is a sign of terrible inadequacies.
