Ottawa residents have four months to adjust their garbage disposal habits before a new three-garbage item limit is imposed on curbside waste this fall.

The City of Ottawa will implement the new three-item limit on Sept. 30, as part of a plan to reduce the amount of waste heading to the landfill and extend the life of the Trail Road Landfill.

“If changes aren’t made to waste disposal habits, the Trail Waste Facility Landfill could reach capacity between 2034 and 2035,” staff say, noting a new landfill or waste-to-energy facility could cost between $350 and $500 million.

The city says a garbage item could be a garbage bag, a 140-litre container or a bulky item.
