O, Canada!

Ferries sink all over the world, but almost nowhere do they do so with no loss of human life.  Apparently, Canada is the exception to the rule.  Now granted, there were only a hundred or so persons on board, rather than the thousands of passengers typical in stories from the south seas or the Indian Ocean or the Baltic; and the ferry didn't go down in a storm, but zero is still O--there can be no upward adjustment when one of the numbers is zero.  Kudos to Canadian mariners.
