Heavy rainfall triggered widespread flooding across Ottawa today, forcing road closures, disrupting traffic, and prompting emergency officials to urge motorists to avoid flooded areas. Flash flooding affected several major routes, including Woodroffe Avenue and portions of Highway 417, as intense rainfall overwhelmed drainage systems across the city.
According to the Ottawa Police Service, Woodroffe Avenue has been closed between Knoxdale Road and Norice Street due to significant flooding. Officers are asking drivers to avoid the area and seek alternate routes while crews assess road conditions and work to restore safe travel. Floodwaters made the roadway impassable, creating hazardous driving conditions for commuters.
Flooding also affected Highway 417, where sections of the roadway experienced standing water following the heavy downpour. Authorities reported flooding near the Holly Acres Road area, while other sections of the highway were impacted by rapidly accumulating water. Motorists encountered delays as emergency responders monitored conditions and transportation officials worked to address affected areas.
The severe weather also disrupted Canada Day celebrations across the nation’s capital. Organizers temporarily suspended activities at several event locations, including LeBreton Flats, because of dangerous weather conditions associated with the storm system. Officials advised attendees to monitor weather alerts and event updates before returning to celebration sites.
Emergency officials continue urging residents not to drive through flooded roadways. Even shallow water can conceal roadway damage
