On October 15, 1954, the remnants of Hurricane Hazel dumped millions of tons of water on Toronto and southern Ontario.
Hazel was projected to dissipate, but instead re-intensifiedunexpectedly and rapidly, pounding the Toronto region with winds that reached 110 km/h.
The storm killed 81 people, left over 2,000 families homeless and caused millions in property damage.
Still, Hazel also changed Toronto in a good way. The Toronto and Region Conservation Authority was created. Rivers have been altered with flood-controlled channels. People can no longer live in areas at risk. Flood plains were turned into conservation areas, creating a greener, safer city.
