Hydro One has not released the names of the victims pending the notification of next of kin, but Pugliese said they were based in different regions from across the province.
The crash happened shortly before noon ET on Kim Clayton's property on Upper Flinton Road.
Clayton said workers had been working on a hydro tower all week, with helicopters going back and forth, and sometimes landing on a field on the property or dropping workers off at the tower.
She was inside her home when she heard the crash and felt her house shake.
She looked outside to see other hydro workers running toward the tree line. She couldn't see the helicopter, nor could she see any smoke or fire, but she said she saw what looked like a piece of the helicopter in one of the trees.
It took ambulances about 15 minutes to arrive at the remote rural location, about 40 kilometres north of Belleville.
