Thousands of people had to go old school and open windows, rather than rely on air conditioning on Thursday evening.

A large chunk of the city was plunged into darkness when power was knocked out from Carleton to the waterfron and from Yonge to the Don Valley Parkway.

More than 6 thousand people were reportedly affected.

Toronto Hydro have suggested that 'best case scenario' would see power restored around 1 o'clock on Friday morning.
