You can now access the Sarnia Waste Calendar right here. No need to try to find the printed waste calendar—it’s always accessible on your computer at LambtonShield.com. Remember, there is now a THREE BAG LIMIT for weekly waste pickup. As in the past, there are two zones–with weekly pickup. The zones are only for recycling purposes. If you live in the area of the city north of Confederation Line and east of Indian Road, you are in Zone 1. All other areas are in Zone 2. You can CLICK HERE for a PDF of the city of Sarnia-issued calendar, which includes information on what’s acceptable and what isn’t for your Blue Box.
