Just under 2000 Hydro One customers in the Parry Sound District will be without power overnight on Oct. 5.
The company says the power will be down for four hours starting at 1 AM until 5 AM.
Officials say the outage will affect customers in Wallbridge, The Archipelago, Harrison, Mowat, Key River as well as the Magnetawan, Henvey Inlet and Shawanaga First Nations.
Hydro one says the power will go offline to allow crews to replace a transformer.
