Changes to the MHSW Common Cost 
Allocation  Methodology
 
The Resource Productivity and Recovery Authority (RPRA) has issued an amendment to the Municipal Hazardous or Special Waste (MHSW) Program Plan that changes how common costs are allocated to material categories to determine steward costs.

As such, Stewardship Ontario is implementing changes to its Common Cost Allocation (CCA) methodology, which will be reflected in steward invoices issued in October 2019.
