There is a significant risk of thunder-freezing-rain tomorrow almost the entire day from 9am to 6pm.
It's good to see so many Ottawa organizations and businesses proactively shutting down for tomorrow morning with potentially severe freezing rain in the forecast. 👍
Ottawa library branches closed Wednesday morning due to the weather forecast
For the safety of our community, we're closing all programs and centres on Wednesday, March 11, 2026 in response to the hazardous weather event warning from Environment Canada.
Please stay safe and continue to monitor trusted sources, including the City of Ottawa.
Environment Canada has issued a freezing rain warning for Ottawa, Gatineau, the Outaouais region, and eastern Ontario starting Tuesday evening or Wednesday morning and continuing for about 24 hours. Hazards: 10 to 30 mm of freezing rain in some areas, heavy rain, icy and slippery roads and sidewalks. Dangerous road conditions expected. The university remains open. However, check your emails before going to class, plan your trips, and take extra precautions!
Important notice.

Significant Weather Event declared: Please exercise caution when using City sidewalks, roads and the winter cycling network. Freezing rain will make surfaces icy and could lead to power outages. Please prepare accordingly and avoid unnecessary travel.
With significant freezing rain forecast for Wednesday, preparations are underway to keep transit operating safely for customers and staff and to ensure transit service can recover quickly when the storm ends. Across the O-Train network, our maintainers, Rideau Transit Maintenance (RTM) and TransitNext, are deploying resources to respond to this severe weather. Maintenance staff will be focused on limiting ice buildup on station and track infrastructure, such as switches, platforms, and high-traffic pedestrian areas. During this weather event, Line 1 will operate every four to five minutes during the morning peak period. The number of trains in operation may be adjusted to help mitigate ice buildup on the overhead wires and tracks. This frequency will also allow for flexibility should additional adjustments be required. RTM has applied de-icing fluid to the overhead wires to help reduce ice buildup and will be running trains with special pantographs to help scrape ice off the wires as the vehicles pass by. O-Train Lines 2 and 4 will operate as regularly scheduled. TransitNext has deployed additional resources to monitor switches and keep platforms and train doors clear of ice.
Bus and Para Transpo services will continue to operate. Road conditions may impact traffic across the city and, as a result, it is possible customers may experience longer travel times. Some trips will be removed from the schedule to maintain priority trips. Customers who have to travel should use real-time travel tools, like the Transit app, to plan their trip in advance. During this freezing rain event, we encourage customers to: Allow plenty of time when planning their commute as the weather can impact everyone on the road. Use caution when boarding and exiting at bus stops or stations. Use real-time travel tools for updates on the status of bus trips, including the Transit app. Sign up to receive alerts by e-mail or text for specific bus routes at octranspo.com/alerts. Follow OC Transpo alert page for the latest updates on service and detour information. Tomorrow’s forecast is expected to create challenging travel conditions for anyone moving around the city. Throughout the weather event we will provide updates to customers on all our communication channels including octranspo.com, social media and via text messages.
Update from @octranspo.com about train, bus, and Para Transpo operations in anticipation of the storm.
"In anticipation of the forecasted freezing rain that is expected to start Wednesday morning (March 11, 2026), all Recreation and Culture drop-in, membership, facility rentals and programs scheduled before noon on March 11 will be cancelled. Facilities will remain closed."

Environment Canada has issued a special weather statement for Ottawa
Freezing rain is expected to begin overnight and continue into Wednesday. Ice buildup on trees & power lines can lead to potential power outages. Our crews are on standby and ready to respond safely and as quickly as possible.
It's astounding to see the success of ÀVélo! They started with only 10 stations and 100 bikes downtown in 2021. Just 5 years later and now reaching into suburban communities (and I think Nadia lost a digit it looks like 225 stations in 2026!).
In a technical briefing, Environment Canada says the track of the system is still unclear but the Ottawa Valley appears most at risk for prolonged freezing rain.

Warmer temperatures and rainfall over the weekend have resulted in rising water levels within the Carp River watershed. The MVCA has changed the Flood Watch status from "yellow" to "orange" 🟠

Looks like there is an update coming tomorrow from the province re: their plan to merge Ontario's conservation authorities. More about the issue here:
open.substack.com/pub/glengowe...
A couple of residents reported bad-smelling stormwater ponds. This is a natural issue caused by low dissolved oxygen in the water. The recent rainfall will help increase oxygen levels and reduce the smell. Several stormwater ponds across the City are experiencing the same conditions right now.
A Special Weather Statement has just been issued for a potential Freezing Rain Event Wednesday in the Ottawa area. #ONStorm
The Mississippi Valley Conservation Authority is hosting a public open house a week from tonight...

Over the past few years, I’ve had more and more conversations with members of Ottawa’s cricket community. The message has been clear. The sport is growing quickly, and we simply don’t have enough places to play. We’re going to fix that.
Cllr. @glengower.ca invited Cllrs. Carr, Curry and I to join his Suburban Legends team for Rotary trivia last night in Stittsville. Third place after a rough start in a packed house! Thanks, Glen - that rocked.
Correct me if I'm wrong please: I am about 99.9999% certain that driverless vehicles are not permitted under any circumstances on public streets or parking lots in Ontario.
It’s definitely puddle season. 26mm of rain fell yesterday in Ottawa. With a current temp of 4° we are still seeing melting. High today 5° under mainly cloudy skies. Wind WSW 20-40. Chance of showers late into early Mon. Low 3°. High Mon 12°. Blustery.

This week’s update on safely restoring capacity on Line 1 and the key performance indicators on our bus action plan is now live.
Access the report here: www.octranspo.com/en...
OC Transpo has been releasing weekly data about bus fleet availability. Here are the latest numbers based on today's update. More electric buses (now up to 56) + working through maintenance backlogs = more buses available for service. Target is at least 520 buses and <0.5% trips undelivered.
