Drivers will have to slow down in Port Dalhousie.
The speed limit will be going down to 40-kilometres per hour, in a handful of residential areas.
This will impact all streets north of Main Street from Courtleigh Road in the west, to Lock Street in the east.
It will also apply to the roads south of Main Street, from Martindale Road in the west and to Lock Street in the east.
This is all part of the Port Dalhousie speed zone pilot project, which was approved by City Council.
More than 50 signs will be going up in the entrances of the affected neighbourhoods, starting tomorrow.
