Flooding at the latter site also created a sinkhole on Bay Street. "Water started gushing up on the road — they had quite the flood for a while — and that caused a sinkhole to develop on Bay," said CBC's Trevor Dunn from the scene.
The intersection was "a wet, muddy mess of broken asphalt and gravel," that could take all day to fix, he added.
The intersection was still completely blocked by emergency crews by about 7 a.m. Crews hope to have at least one lane reopened by late morning or early afternoon.
The city felt its first cold snap of the season overnight, as temperatures dipped below freezing and stayed there into the morning.Suggest a correction
