The Canadian utility company Hydro One said about 10,000 people are in the dark
Around 10,000 people in downtown Toronto have been left without electricity after a major outage.
Hydro One, which supplies hydroelectric power to the Canadian city, said it had put “all hands on deck” to discover the cause of the fault.
A spokesperson told CBC News that the company is investigating reports that the outage was caused by a construction crane touching an overhead power cable while being carried on a barge.
