To promote residential water conservation and efficiency, the City of Cornwall has developed a rebate program for residents who replace high-flow toilets (13L per flush or more), with WaterSense® certified low-flow toilets. To learn more about the program, click here. To learn more about WaterSense® labelled Toilets, click here.

A $50 rebate will be awarded for each toilet replaced up to a maximum of two (2) toilets per household. To be eligible for the toilet rebate, the following mandatory criteria must be met:

  • The property where the toilet is being replaced was constructed prior to 1997
  • The property is within City limits and is serviced by the municipal water supply
  • A 13L or more per flush toilet has been replaced with a WaterSense® certified toilet

Please note: the program only applies to toilets purchased after June 1, 2022. 

Look for the REBATE ELIGIBLE sticker or the WaterSense® label.
