TORONTO, MONTH DATE , 2023 -With a number of regions under active flood warnings, Hydro One is reminding Ontarians in flood prone areas about the importance of preparing their homes, including an emergency kit, along with the steps to take if flooding occurs.

"Preparing for an emergency starts with understanding the risk to you and your family and putting plans in place to remain safe, which may include leaving your home if water levels rise to potentially dangerous levels," said Teri French, Executive Vice President, Safety, Operations and Customer Experience, Hydro One. "We are monitoring rising water levels across the communities we serve and will respond as safely and quickly as possible to disconnect power as required to keep customers safe."

Move water away from your home

Hydro One encourages residents to keep water away from their home by removing debris from gutters, eavestroughs and downspouts. Residents should also inspect the foundation of their home for any cracks that may need to be repaired. If you have a sump pump, maintain it regularly so it's ready if you need it and consider a backup power source, such as a battery or generator.

Water and electricity do not mix

If flooding occurs at home and water starts to reach electrical outlets, baseboard heaters or furnace, residents should call their electricity utility to have power safely turned off. Residents should not enter any flooded areas, such as the basement, until power is disconnected.

Restock your emergency kit

It is critical to ensure you and your family are prepared in case of an emergency or extended power outage. Your emergency kit should include enough food and water for all family members, a first aid kit and any necessary medical items, emergency numbers, blankets, cash, a battery-powered radio and flashlights along with extra batteries.

Supporting our customers

Hydro One customers experiencing flooding are asked to call 1-800-434-1235 to have their power disconnected. To support customers during challenging time, Hydro One automatically waives all connection fees along with delivery fees when power is disconnected due to flooding.
