This trap catches vehicles coming southbound on Winston Churchill Blvd down the big hill just before (north of) Royal Windsor Drive. The officer will sit in a mechanic’s driveway and your view of him is obscuring by the GO train track overpass. Watch your speed coming down the big hill just before the train tracks and you will be fine. Alternatively, the officer will sit right at the foot of the high at the Shell station, north of the train tracks.
