There are at least 3 areas of speed traps along Guelph Line north of Dundas Rd to Derry Rd. The most common spot is at Mount Nemo Conservation Area in their driveway or across Guelph Line on Colling Road. I drive this road every day to work and see at least two people a week pulled over. They also sit on Britannia at the church, in Lowville, and sometimes in the Bluffs (the mega-homes). I golfing season this speed trap is nearly daily and if not here then on Cedar Springs. I do not speed more than 10kph over the limit as a coworker was ticketed for 97 in an 80 zone. The speed limits go from 80 to 60 to 50 from Dundas to Lowville.
