Some people living in northwest Toronto have been among the last to have their power restored after a storm hit the city two days ago.

Hydro crews have been working around the clock to repair the damage done on Tuesday night. Officials said the messy snow and ice mix, coupled with salt spray kicked up from the roads, caused electrical fires across the city.

Similar pole fires are common in the winter months, but Toronto Hydro is used to dealing with one every two weeks or so, not 50 in one night, its CEO said Wednesday.

"There is no doubt that progress is being made," said Toronto Hydro CEO Anthony Haines, referring to the repair efforts.

Eighty-seven thousand customers were without power at the height of the problems on Tuesday. That equated to some 250,000 residents of Toronto.

A day later, a few thousand customers were without power and by Thursday, the number of customers affected was in the hundreds.
