 In 1954, Hurricane Hazel devastated the Humber Valley and Humber Bay was one of the worst-hit areas, however because of the loss of so much of the residential area around the old Lake Shore/Queensway intersection, the damage was largely to city infrastructure notably destroying the Lake Shore and Royal York bridges over the Mimico Creek and damaging the Lake Shore Bridge over the Humber.Etobicoke became a Borough and was reunited with Mimico, New Toronto, and Long Branch.With city highway expansion plans the City of Toronto extended the Provincial Queen Elizabeth Highway into the City of Toronto with the building of the Gardiner Expressway along the top of Humber Bay.
