Proceeding south on Harmony Rd south of Olive Avenue you cross a railway overpass.. At the end of the down incline is a street on the right. The officer will sit there and use radar to trap you. This typically happens at morning rush hour as it is a high volume road which ends as an entrance to the 401 Westbound. They do however also enforce at other times of the day. The posted limit is 60 Km’s/hr but is a two lane in each direction and traffic flow is usually 70 – 80 kms/hr
