Quebec Power Outages
Canada has no open live feed, so the quickest way to check Quebec is the official outage map from Hydro-Québec and Hydro-Sherbrooke.
Hydro-Québec, owned by the Québec government, has 4.65 million customer accounts, and municipal systems such as Hydro-Sherbrooke serve a few cities. Hydro produced 94% of 2023 generation. Freezing rain and trees are the signature risks: the January 1998 ice storm left nearly 1.4 million customers in the dark, and the April 2023 ice storm cut power to about 1.125 million. The Régie de l'énergie regulates distribution, and Hydro-Québec publishes a live outage API.
