One person is in hospital in serious condition after 20 e-bikes caught on fire in a residential underground parking garage on Monday.

Toronto Fire were called at 12:30 a.m. to 564 Eglinton Ave. W., just east of Spadina Ave., for the three-alarm blaze.

“We responded to reports of a fire at an underground residential building,” said District Fire Chief Dan Vieira.

“We found a bunch — 20 e-bikes — on fire and we cleared the smoke and got the fire out. One tenant was taken to hospital.”

The person has serious but non-life-threatening injuries.

Damages are still being assessed.

There was no immediate word on who owned the e-bikes or why there were so many.
