A power outage that affected Toronto's waterfront, including Billy Bishop airport, has been resolved.
The outage, which started at about 10:30 a.m. on Tuesday, was concentrated along the waterfront and on Toronto Islands.
It ended at 3 p.m.
Sarah Sutton, spokesperson for PortsToronto, which owns Billy Bishop Airport, said operations ran as scheduled due to an "airport-specific auxiliary power system" although there may have been some delays or cancellations during the outage.
Toronto Hydro, meanwhile, continues to investigate what caused the power outage, said its spokesperson, Tori Gass, Tuesday afternoon.
Gass said she did not know how many people were affected by the power failure.
