Ancaster, Ontario Traffic and Road Conditions

How to use the Ancaster Traffic Map

Traffic flow lines: Red/White dashed lines = Closed Road, Red lines = Heavy traffic flow, Yellow/Orange lines = Medium flow and Green = normal traffic. Black lines or No traffic flow lines could indicate a closed road, but in most cases it means that either there is not enough vehicle flow to register or traffic isn't monitored. Also, If you do not see traffic flow, you can zoom in closer to reveal localized data. If you are unable to pan the map, press here (to focus off of the map) and try again.

Traffic Incidents: Each image represents a traffic event or incident such as road construction, closure or accident. For example, a Red Circle with a White line marks a closed road.
