How accurate is the live traffic data?

Traffic data comes from TomTom, which processes billions of GPS data points daily from connected vehicles. Data is updated every 5 minutes with confidence scoring. Ontario road events come from the official 511 system.

Which highways are covered?

We cover major Canadian trucking corridors (401, 400, QEW, 403, Trans-Canada) and US Interstate highways (I-90, I-94, I-75, I-81, I-95). Custom location checks are also available.

Does this show construction and closures?

Yes. For routes through Ontario, we pull real-time construction, closure, and incident data from Ontario 511. These appear as markers on the map alongside traffic flow colors.
