Ottawa's Canada Day celebrations were washed out — literally — after the city was drenched with 118 millimetres of rain on July 1, 2026, causing widespread flooding, power outages, and the cancellation of festivities that tens of thousands of residents had been looking forward to.
A Record Soaking
The rainfall that hit Ottawa on Canada Day was nothing short of extraordinary. Environment Canada classified the event as "extreme weather," and the numbers back that up — 118 mm in a single day is a significant deluge for the capital. By comparison, Ottawa's average rainfall for the entire month of July is typically around 90 mm. Roads across the city flooded rapidly, with some areas becoming impassable as storm drains struggled to keep up with the sheer volume of water.
Hydro Ottawa reported power outages affecting neighbourhoods throughout the city as the storms moved through, leaving residents scrambling. Cleanup crews were deployed across Ottawa as soon as conditions allowed, working to clear debris, pump out flooded areas, and restore normalcy.
Fireworks and Festivities Cancelled
The extreme weather put a definitive end to Canada Day programming across the city. The signature Parliament Hill fireworks — one of the most beloved annual traditions in the capital — were cancelled, along with outdoor concerts, family activities, and other events that had been planned along the riverfront and in city parks.
For many Ottawa families, the Canada Day washout was a genuine disappointment. The holiday is typically one of the city's biggest celebrations, drawing massive crowds to the downtown core and ByWard Market area. This year, however, residents were advised to stay off roads and away from low-lying areas as the storms rolled through.
The heat wave that had baked Ottawa in the days leading up to Canada Day gave way dramatically to the severe storm system, catching many residents off guard by the intensity of the switch.
Southern Ontario Hit Hard
Ottawa wasn't alone in taking a beating. The same storm system slammed southern Ontario broadly, with damage reported across multiple communities. The Weather Network flagged the system as one of the more significant Canada Day weather events in recent memory for the region.
Cleanup Continues
As of July 2, city crews are continuing cleanup efforts. Residents in affected areas are being urged to report flooding, downed trees, and road damage through the city's 311 service. Ottawa Public Works has been prioritizing the most heavily impacted streets and infrastructure.
While the Canada Day fireworks can't be rescheduled, the city has not yet announced any plans for a makeup celebration. Residents hoping to mark the occasion may want to keep an eye on City of Ottawa announcements in the coming days.
In the meantime, the silver lining — if there is one — is that Ottawa's parks and green spaces will be well watered heading into the summer.
