Ontario 511 Cameras — Live Road Cameras & Map
All Ontario 511 cameras — interactive statewide map
About this map
Ontario is built around its highways, and almost all of them are watched by cameras. The provincial system, Ontario 511 (511on.ca), pulls live images from more than 900 cameras across the network the Ministry of Transportation maintains — heaviest along the 400-series freeways and the QEW in the south, and following the Trans-Canada (Highways 17 and 11) across the north. Our map gathers those official feeds into one fast, searchable view so you can look at the actual road before you commit to a drive, whether that's a Friday-night crawl out of the GTA or a long winter haul north of Lake Superior.
This map is cameras-only, and that's worth being clear about. Ontario 511 does not publish a road-weather data feed, and our temperature and road-sensor supplement covers the United States only — so you will not see a thermometer reading or a pavement-sensor number on any Ontario camera here. What you do get is the picture itself, and the picture is the signal: a live still tells you whether the 401 is moving or parked, whether a snow squall has turned Highway 402 into a whiteout, whether there's slush on the QEW or bare-and-dry pavement on the way to Niagara. For an actual forecast — temperatures, squall watches, freezing-rain warnings — check Environment Canada before you go.
Use the area presets to jump straight to the part of the province you care about: Toronto and the GTA, Niagara and Hamilton, Ottawa, London and Windsor, Barrie and Muskoka, Kingston and the 1000 Islands, or Northern Ontario. Search a highway number or a city name, star the cameras you check most, and treat each image as a recent gut-check rather than an official record. For closures, collisions and construction, Ontario 511 itself (call 511 or visit 511on.ca) is the authority.

Province-wide
The province-wide view zooms out to the whole network at once — the dense 400-series and QEW cluster across the south, Ottawa in the east, and the thin Trans-Canada thread (Highways 17 and 11) running through Sudbury, Sault Ste. Marie, North Bay and Thunder Bay in the north. Use it to scan Ontario end to end before a long trip, then drop into a regional preset. Remember the map is cameras-only: the image shows you snow, slush, backups or whiteouts, but there is no temperature or road-sensor readout here — get forecasts from Environment Canada.
Toronto & the GTA
This is the busiest cluster of cameras in the country, covering the Greater Toronto Area and the 400-series core: Highway 401 — the busiest highway in North America, carrying well over 400,000 vehicles a day through the city — plus the 400 north toward Barrie, the 404 and the Don Valley Parkway, the 427, the Gardiner Expressway along the waterfront, and the QEW heading west. It reaches across Mississauga, Brampton, Markham and Vaughan. Chronic congestion is the rule here, so the cameras are most useful for seeing exactly where the 401 is parked before you choose a route. There's no weather readout — the image is the signal.
Niagara & Hamilton
The QEW (Queen Elizabeth Way) anchors this region, sweeping around the western end of Lake Ontario from Toronto through Burlington and Hamilton, then through St. Catharines to Niagara Falls and Fort Erie at the Peace Bridge border crossing to the United States. Highway 403 ties Hamilton into the network. Cameras here cover the Niagara tourist run and the Golden Horseshoe commute; in winter, watch for squalls and slush coming off Lake Ontario and Lake Erie. The live image shows backups and road surface — for a forecast, check Environment Canada.
Ottawa
Ottawa's spine is Highway 417, the Queensway, which runs east–west through the capital and continues to the Quebec border as Autoroute 40 toward Montreal. Highway 416 (the Veterans Memorial Highway) drops south from the city to meet Highway 401 between Brockville and Cornwall, the fast link toward Toronto. Cameras cover the Queensway through Kanata, Nepean and Orléans plus the 416 corridor. Winters here bring heavy snow and freezing rain, so the camera image is your read on whether the road is bare, wet or snow-covered — pair it with an Environment Canada forecast.
London & Windsor
Southwestern Ontario's freeway triangle lives here: Highway 401 running Windsor–London–Toronto, Highway 402 connecting London to Sarnia and the Blue Water Bridge, and Highway 403 through the Kitchener–Waterloo–Cambridge and Brantford area. This is prime snowbelt country — lake-effect squalls off Lake Huron routinely slam the 401 and 402 near London and have caused some of Ontario's worst multi-vehicle pileups in sudden whiteouts. The cameras let you spot a squall band or a backup in real time; there's no weather readout, so confirm conditions with Environment Canada before driving.
Barrie & Muskoka
This is the cottage-country corridor: Highway 400 north from Toronto through Barrie toward Parry Sound and Georgian Bay, and Highway 11 carrying on through Orillia, Gravenhurst, Bracebridge and Huntsville into Muskoka. Summer-weekend traffic is the headache here, while winter brings intense lake-effect snow squalls off Georgian Bay that can shut stretches of the 400 and 11 with little warning. The live cameras show you whether the drive up is flowing or stalled and whether a squall has hit — but for snowfall forecasts, rely on Environment Canada.
Kingston & the 1000 Islands
Eastern Ontario follows Highway 401 from Kingston east through the scenic 1000 Islands region, past Gananoque, Brockville and Cornwall to the Quebec border, where the 401 becomes Autoroute 20 toward Montreal. This is the main Toronto–Montreal artery and a busy truck corridor. Snow squalls and freezing rain regularly close sections of the 401 around the Kingston–Belleville stretch in winter. Cameras give you a live look at whether the corridor is clear or blocked; there's no temperature or sensor data on the map, so check Environment Canada for the forecast.
Northern Ontario
North of the populated south, coverage follows the Trans-Canada — Highway 17 along Lake Superior and through Sudbury and Sault Ste. Marie, and Highway 11 through North Bay and the northeast — out to Thunder Bay. These are long, remote, largely two-lane stretches with limited services, sharp curves, wildlife at dawn and dusk, and severe winters. Cameras are spaced far apart but invaluable for confirming a remote pass is open and plowed. The image is all you get here — no weather readout — so plan around an Environment Canada forecast and the 511 closure list before committing to a northern drive.
Tips for using Ontario road cameras
- Check the camera nearest your trouble spot, not your starting point. The 401 can be bare and moving where you are and parked in a whiteout 40 km ahead — tap the camera closest to the squall, the interchange or the backup you're worried about.
- Remember this map is cameras-only. There is no temperature, no pavement-sensor reading and no road-weather feed for Ontario — the live image is the signal. For an actual forecast, including snow-squall and freezing-rain watches, check Environment Canada before you leave.
- Respect the snowbelts. Lake-effect squalls off Lakes Huron and Georgian Bay can turn the 401, 402 and 400 from clear sky to total whiteout in minutes near London, Sarnia, Barrie and Owen Sound — a leading cause of Ontario pileups. If cameras up the road look white, wait it out.
- For GTA congestion, scan a string of 401 cameras before you choose a route. Seeing where the red actually starts lets you bail to the 407, the DVP or surface roads before you're stuck in it.
- Use the area presets and search box. Jump to Toronto, Ottawa or Northern Ontario with one tap, or search a highway number like '401' or '417' or a city like 'Kingston' to pull up the relevant cameras fast.
- Treat the cameras as a gut-check, not the official word. For confirmed closures, collisions and construction, Ontario 511 (511on.ca or dial 511) is the authority — especially on the remote northern Trans-Canada, where a single closure can mean a very long detour.
