The Waste Diversion Act, 2002 is Ontario’s main legislation to promote the reduction, reuse and recycling of waste through the development, implementation and operation of waste diversion programs. Over the past few years much progress has been made on waste diversion in Ontario. Programs initiated and developed under the Waste Diversion Act are changing the way we approach waste diversion. These initiatives have incorporated, to varying extent, principles associated with extended producer responsibility, which hold that producers should be responsible for the costs associated with the environmental impact of their products. Much more needs to be done. Stakeholders have identified a number of challenges associated with the existing waste diversion framework, the programs that have been approved, and the Act itself. Many feel that it is time to reflect on the approaches Ontario has taken, consider how best to undertake future waste diversion initiatives, and define what kind of a future we should drive toward, as a society.
