Here’s what you need to know about food, shelter and dealing with the power outage.
Living with a power outage
The Canadian Red Cross recommends listening to a battery-powered or wind-up radio to stay informed, and keep emergency numbers near your landline telephone.
Appliances and electronic equipment should be turned off to prevent damage from a power surge when power is eventually restored.
As for lighting, candles pose a fire hazard so authorities recommend using flashlights instead.

With hydro crews working feverishly to restore power, you can lend them a helping hand by keeping one light inside and one light outside turned on, so that they can tell when power has been restored to your home.
The Red Cross suggests avoiding travelling by car, because traffic lights will be out and road conditions may be hazardous.
Downed power lines are a common sight in many parts of the Ottawa region this weekend. Hydro Ottawa urges people to assume that all downed power lines are live and dangerous.
If you’re using a generator, Hydro Ottawa recommends doing so outdoors because exhaust fumes can cause carbon monoxide poisoning in the absence of proper venting.
Food
Ottawa Public Health recommends keeping refrigerator and freezer doors closed unless absolutely necessary. An unopened refrigerator can keep foods cold for around four hours without power, while a freezer can keep food frozen for up to 26 hours if its door remains closed.

Thawed food that has been sitting at room temperature for more than two hours should be thrown out, according to Ottawa Public Health, which calls for a “When in doubt, throw it out” approach towards dealing with food.
Officials on Saturday urged people in the Ottawa area to stockpile food and water.
