On July 3, 2026, severe thunderstorms swept across southern Quebec, leaving more than 35,000 Hydro‑Québec customers without electricity. The intense weather system brought damaging winds that knocked out service across a broad area, prompting the utility to issue an outage alert for the region.
Hydro‑Québec confirmed that the storm‑related damage disrupted the power grid, affecting tens of thousands of households and businesses. The utility’s statement noted that the outages stemmed directly from the high‑velocity winds associated with the thunderstorms, which caused lines and equipment to fail.
The storms moved rapidly through the southern part of the province, producing widespread damage beyond the loss of electricity. Residents in the affected zones reported the loss of lighting, heating and refrigeration as the power interruption continued. Many also faced the challenge of limited communication options while waiting for service to be restored.
As the day progressed, the extent of the outage remained significant, with Hydro‑Québec tracking the number of customers without power at over 35,000. The utility’s response focused on monitoring the situation and providing updates to those impacted, while the full scope of repairs required assessment of the damaged infrastructure.
Authorities and utility officials emphasized the seriousness of the weather event, noting that the combination of severe thunderstorms and strong winds can produce rapid and extensive disruptions to essential services. Residents were advised to exercise caution, conserve any remaining power supplies and stay informed through official channels as restoration efforts continued.
The incident highlights the vulnerability of the region’s power network to extreme weather and underscores the importance of preparedness for future storms that may similarly affect large numbers of customers across southern Quebec.
