People searching for "90 day shutdown Canada" usually want to know whether the power grid could be shut down for months. Here is what the term means, what was reported, and what is realistic.
What a grid shutdown means
A grid shutdown is a widespread loss of electricity across a large area, not a street or neighbourhood outage. It could come from severe weather, equipment failure, a cyberattack or physical damage. Most outages in Canada are local and last hours to a few days.
What was reported
The "90 day" figure comes from press reports that the Pentagon wants major US bases able to run for at least 90 days without outside electricity, fuel or water. It describes how long a base would be expected to operate on its own. See our explainer for the sources. No Canadian government or utility has announced a 90 day shutdown.
What is realistic in Canada
The longest Canadian outages in recent history came from ice storms and severe weather, and lasted days to a few weeks in the worst-hit areas. Read more on how long outages last and the ice storm guide.
How to prepare
- Two weeks of water and food is a strong, achievable target. See the week-long outage plan.
- Know your heat plan. In winter, heat is the biggest risk, see what to do if the power is out for a month.
- Keep a battery bank or power station for phones, lights and a radio.
