Before the recent hydro Ottawa outage, residents and businesses in Ottawa and Casselman expected reliable electricity from Hydro Ottawa Limited, which has been a trusted provider for over a century. However, on March 17, 2026, a combination of flash freezing and high winds led to widespread outages across the service territory.
During the peak of the storm, approximately 26,000 customers experienced a loss of power. This sudden disruption marked a significant shift from the usual stability that Hydro Ottawa is known for. As of 2 p.m. on the same day, power had been restored to 24,200 customers, leaving 1,800 still without electricity.
The direct effects of this outage have been felt across the community, with many residents advised to conserve energy as repairs continue. Hydro Ottawa has prioritized restoring power to areas with serious safety hazards and critical infrastructure, emphasizing their commitment to community safety during these challenging conditions.
Hydro Ottawa has urged the public to respect work site perimeters and to stay away from downed power lines, highlighting the importance of safety amid ongoing restoration efforts. “Safety remains the number one priority amid these windy conditions,” a spokesperson from Hydro Ottawa stated.
As the utility company works diligently to restore power, they have reminded customers of their 24/7 outage hotline at (613) 738-0188 for reporting outages. The community’s patience has been crucial during this time, with Hydro Ottawa expressing gratitude for the understanding shown by residents.
With approximately 372,000 homes and businesses served by Hydro Ottawa, the impact of the outage is significant, affecting a large portion of the population. Experts suggest that such weather events may become more frequent, necessitating ongoing improvements to infrastructure and emergency response strategies.
As restoration efforts continue, residents are encouraged to stay informed and prepared for any further developments. The situation remains fluid, and details remain unconfirmed as Hydro Ottawa works to restore power to the remaining customers.
