What is a Sanitary Landfill Site?
A sanitary landfill site is a waste disposal facility where waste is deposited into the ground and covered. All sanitary landfill sites in Ontario are regulated and monitored by the Ministry of the Environment.

Landfill Operations
The Town of Caledon operated the Caledon Sanitary Landfill Site (CSLS) from 1968 until July of 1976. The Region of Peel took over site operations in 1976, but the Town of Caledon still maintains ownership of the site today.

The landfill site is approximately 20 hectares (45 acres) in size. In 2000, the landfill accepted 13,205 tonnes of waste. This waste is primarily generated within the Town of Caledon. Landfill operations will continue until approved contour levels have been reached.
Environmental Monitoring and Controls
All waste at the site is compacted to reduce volume and water filtration. The process of compaction reduces the production of methane gas and leachate, both of which are produced through the natural decomposition of waste. On-site there is a continuous groundwater monitoring program.
Active Landfilling Area
The Active Landfilling Area is where residents and businesses can dispose of their non-recyclable waste. This can be particularly helpful to residents when they have larger amounts of waste, or materials too heavy to put out at the curb.
