Crews respond to a fire under the Gardiner Expressway

Fire crews were spotted attending to a blaze underneath the Gardiner Expressway on Saturday afternoon.

Authorities were initially called about an encampment fire near Spadina Avenue and Lake Shore Boulevard West just after 1:00 p.m.

While an investigation is still ongoing, Toronto Fire Services have ruled out the encampment as the cause of the blaze. No injuries were reported.

Footage taken by CityNews in the downtown core appears to show a plume of smoke rising from underneath the highway.

Authorities say the fire has been extinguished and crews will remain on scene to clear the smoke.

All lanes were reopened by 4:30 p.m.
