The still-rising Ottawa River has not yet peaked, with a surge in the number of people who have gone to western Quebec’s largest city for help.
- COMING UP | CBC Radio One has a live Ottawa-Gatineau flooding special from 12 to 1 p.m. ET. Listen online, on the CBC Radio app or 91.5 FM.
The city of Gatineau said this morning 1,212 people have registered as flood victims, representing 575 homes.
This represents a rise of about 200 people from Saturday morning and nearly 500 people in the last 48 hours.
There are states of emergency in at least 13 communities in the region, including Ottawa and Gatineau.
Millions of sandbags have been distributed across the Ottawa-Gatineau area’s riverside communities, with the military expected to start helping residents in Clarence-Rockland, Ont., just east of Ottawa, today.
According to the Ottawa River Regulation Planning Board’s Sunday morning update, the rise in water levels has slowed because of cool temperatures and less rainfall than the upper limit of this weekend’s forecast — Ottawa got 13.4 millimetres of rain compared to a ceiling of 35 millimetres, for example.
According to its forecast, which depends on a number of factors and is “subject to a high degree of uncertainty,” water levels should peak on Tuesday or Wednesday.
The City of Gatineau said water levels were at the 100-year flood threshold in Aylmer, Hull and Pointe-Gatineau, with levels in Masson-Angers to the east less than 10 centimetres from that level.
An update from that city is expected at 1:30 p.m. ET.
The Chaudière Bridge, one of five bridges across the Ottawa River in Ottawa-Gatineau, is now closed.

The city of Ottawa has moved its volunteer registration centre for western areas to the Dunrobin Community Centre on the Thomas A. Dolan Parkway, which is open from 9 a.m. until 7 p.m. today.
Non-emergency boats are now banned from the Ottawa River between the capital and the Carillon dam on the Ontario-Quebec border, under the order of Minister of Transportation Marc Garneau.
Boaters caught breaking this ban could be fined up to $5,000.
Garneau’s office said in a news release drones are not allowed to fly within nine kilometres of flooded parts of Quebec and mentioned the possibility of further airspace restrictions if air evacuations become needed.
Ottawa’s deputy mayor tweeted a model showing how far floodwaters are expected to reach into one area of Cumberland, near the city’s eastern border.
Residents in Cumberland will be getting a knock on their door with this Community Advisory flyer today. <br><br>Emergency personnel hope this visual will encourage home owners to plan appropriately. Water levels have already put many homes at risk.<a href=”https://twitter.com/hashtag/OttCity?src=hash&ref_src=twsrc%5Etfw”>#OttCity</a> <a href=”https://twitter.com/hashtag/Ottnews?src=hash&ref_src=twsrc%5Etfw”>#Ottnews</a> <a href=”https://twitter.com/hashtag/Ottflood?src=hash&ref_src=twsrc%5Etfw”>#Ottflood</a> <a href=”https://t.co/yQYlwriM4H”>pic.twitter.com/yQYlwriM4H</a>
Local conservation authorities have started to flag the possibility of 20 to 30 millimetres of rain on Wednesday and Thursday, just as water levels on the Ottawa River are expected to be peaking.
Further south, the Cataraqui Region Conservation Authority in the Kingston and Brockville, Ont., area is warning water levels in the St. Lawrence River and Lake Ontario systems are expected to keep rising rapidly this week.
It said water levels could be a problem in some areas.
In 2017, docks and some homes in that area were affected by floods.
