What’s watching Ontario
These aren’t red-light cameras. Automated license plate readers like Flock Safety’s photograph every plate that passes, log the time and place, and store it in a searchable database that’s often shared far beyond Ontario — here’s where that data goes. Counts cover cameras reported closest to Ontario (within ~20 km), so nearby towns share the same corridors. Spot one that’s missing? Report it on DeFlock.
