Updated for winter travel ¡ Road closures & live traffic maps
When winter weather hits, closures can roll in fast â and drivers often waste time bouncing between social posts, screenshots, and group chats that may already be out of date. Thatâs why police in parts of Ontario have been pointing motorists to a single, map-based source for closures and hazards: Municipal 511. The idea is simple: one place to check, refreshed in near real time, so you can decide whether to delay, reroute, or stay put.
Below is a practical guide to what Municipal 511 shows, how to read it quickly, and the best equivalent âofficial mapâ options if youâre in Michigan or travelling around Ottawa.
Ontario: Why Municipal 511 is getting promoted during closures
During heavy snow and blowing visibility, the biggest problem for drivers is uncertainty: which roads are actually closed, which routes are âlocal traffic only,â and which hazards are active right now. Police services across several Ontario counties have been directing the public to Municipal 511 because it consolidates closure info into one map view, reducing confusion when conditions change quickly.

What you can check in under 30 seconds
- Road closures (including different closure types, depending on the municipalityâs settings).
- Winter road conditions and hazard markers that can affect travel planning.
- Live/near-live context such as traffic disruptions, construction zones, and reported incidents (varies by region).
- Quick reroute decisions: zoom to your corridor and scan for closure icons before you leave.
Pro tip: If youâre travelling on provincial highways (400-series routes, major corridors), also cross-check the province-wide feed on Ontario 511, which includes highway closures, cameras, and broader regional travel conditions.
Ottawa: Best âlocal viewâ for traffic cameras and incident context
If your commute runs through Ottawa, youâll often want camera context â not just a closure icon. The City of Ottawaâs traffic map is built for that: it provides a live map experience with selectable layers and camera locations across the city network.

When to use which map in Ottawa:
⢠Use Ottawaâs Traffic Map for city-street cameras, congestion points, and local travel patterns.
⢠Use Ontario 511 for highway corridors feeding Ottawa (and broader regional disruptions).
⢠Use Municipal 511 when closures are being posted through participating municipal/OPP channels and you want the âone-stopâ closure view.
Michigan: The closest equivalent is MDOTâs Mi Drive
Municipal 511 is Ontario-focused, so if youâre writing for Michigan readers (or cross-border travellers), the most useful âofficialâ map to reference is Mi Drive, run by the Michigan Department of Transportation. Itâs designed for planning around winter travel disruptions by showing incidents, cameras, construction, and route conditions on an interactive map.

A simple Michigan travel-check routine
- Check the Mi Drive map for your route corridor and camera snapshots.
- Scan for incidents and slowdowns before choosing an alternate route.
- If conditions worsen, assume closures and secondary crashes can appear quickly â recheck right before you leave.

- Lead with the problem: closures change fast; social posts lag.
- Deliver the fix in the first paragraph: Municipal 511 (and your local equivalents).
- Add a quick âwhen to use which mapâ section for local relevance (Ontario vs Ottawa vs Michigan).
- End with a safety reminder: closures exist for a reason; recheck before departing.
Reminder: Even if roads look clear where you are, conditions can be dramatically different 10â20 minutes away in a snow band. Check the map once when you start planning, and again right before you head out.
