Google Maps and Radar Detector Alerts: What Drivers Should Know

Google Maps may display reported traffic and camera information in supported areas, but it does not detect police radar signals. A separate detector is a distinct device subject to provincial law.

A Google Maps radar detector search often reflects a wish to get speed-camera or enforcement alerts in navigation. Google Maps is a navigation app: map reports are not live radar detection and may vary by market, settings and user reports. A dedicated radar detector listens for radar signals; neither tool guarantees an alert before enforcement. In Canada, radar detectors are permitted in British Columbia, Alberta and Saskatchewan (commercial vehicles are restricted in Saskatchewan) and prohibited in Ontario, Quebec, Manitoba, Nova Scotia, the territories and the remaining provinces. Follow posted limits and do not handle a phone while driving.
