Going Southbound on Islington before the 401 (going towards Rexdale Mall) once you go over Elmhurst and pass the cross-walk they are cops usally waiting for you at the bottom of the hill with the radar gun at the street at the bottom of the hill. Same with going Northbound on Islington once you pass Rexdale mall they are waiting on top of the hill right at the cross-walk on the street. 50km zone.
