Ottawa is still digging out from a run of powerful Canada Day storms that knocked out traffic signals, flooded low-lying streets, and left electrical hazards scattered across the city.
Traffic Signals Take the Biggest Hit
The most visible sign of the storm's aftermath has been at Ottawa's intersections. City crews reported roughly 100 traffic signal issues in the immediate aftermath, ranging from signals stuck on blinking red to full outages that turned busy intersections into four-way stop chaos. By Friday afternoon, the city said most of those signal problems had been resolved, though a handful of trouble spots remained under repair as crews worked through the backlog.
For commuters, that meant several days of extra caution at intersections that would normally be humming along on automated timing. Ottawa police and by-law officers were seen directing traffic at some of the worst-hit corners while repair crews worked to restore power and reset the signal controllers.
Downed Trees and Flooded Streets
Beyond the signals, the storms left their mark across Ottawa's neighbourhoods in more familiar ways: toppled trees blocking roads and sidewalks, branches tangled in overhead wires, and pooling water in spots where storm drains couldn't keep pace with the sudden downpours. Public works crews have been working street by street to clear debris and pump out flooded sections, with some residential streets seeing standing water for more than a day after the rain stopped.
Electrical hazards were a particular concern for the city, with crews flagging downed lines and damaged equipment for priority response. Residents were urged to steer clear of any wires resting on the ground or draped over trees, regardless of whether they appeared live.
Why This Matters for Ottawa Residents
Canada Day storms are nothing new for the capital, but the scale of this year's damage — with signals out at roughly 100 spots across the city — underscores how quickly a single severe weather system can strain Ottawa's infrastructure. For a city that leans heavily on synchronized traffic signals to keep its arterial roads moving, even a short-term outage at dozens of intersections ripples into delays across the network, from Kanata to Orleans.
The cleanup also serves as a reminder for Ottawa residents to keep an eye on tree cover near their own properties, especially older trees along boulevards that are more prone to snapping limbs in high wind. City forestry crews have said they'll continue assessing storm-damaged trees on public land in the coming weeks, with removals prioritized based on safety risk.
What's Next
With most traffic signals back online, the city's focus is shifting to longer-term cleanup: hauling away downed branches, patching washed-out shoulders, and completing safety checks on any electrical equipment that took a hit during the storms. Residents who spot ongoing hazards, including trees still leaning on wires or intersections without working signals, are encouraged to report them through the city's 311 service.
