Disasters with highest death tolls
Great Porcupine Fire
The Great Porcupine Fire of 1911 was one of the most devastating forest fires ever to strike the Ontario northland. Spring had come early that year, followed by an abnormally hot dry spell that lasted into the summer. This created ideal conditions for the ensuing disaster, in which a number of smaller fires converged. Official counts list 73 dead, though it is estimated the actual toll could have been as high as 200.
