Water utility deferral program

The City of Ottawa offers a deferral program for water utility bills for low-income seniors and low-income people with disabilities. Under the program, payment of water bills is deferred for applicants who meet the current program requirements.  The City also offers a property tax deferral program for low-income seniors and persons with disabilities.

Before you begin

An initial application for tax deferral may be made at any time during the year for which the tax deferral is sought and shall be made no later than December 31 of that year.  An application to renew the tax deferral must be made annually and must be made no later than the 30th day of September in the year for which the deferral is sought. 

The applicant agrees to provide the necessary information to the municipality in order to demonstrate that eligibility requirements have been met. The applicant also signs a waiver providing the municipality access to personal information for the purpose of confirming eligibility.  


Interest on the deferred amounts will be charged at the rate of 5% per annum. 


The unpaid water deferral shall become due and payable at the earliest of the following dates:

  • the applicant(s) no longer meets eligibility criteria such as income;
  • the property is sold or transferred;
  • upon the death of the applicant, unless the applicant is survived by a spouse who continues to qualify for deferral (The water deferral cannot be transferred to the estate of deceased owner(s));

Deferral amounts represent a lien against the property under provisions established under Subsection 319 (4) and Section 349(3) of the Municipal Act 2001 as amended.


  • If the property is owned by more than one person who are not spouses, then all owners must apply and qualify.
  • Applicant(s) must have continuously owned the property within the City of Ottawa for at least one year before applying for the deferral.
  • The property must be the principal residence of applicant(s).
  • Property must be assessed in the residential/farm property tax class
  • The applicant(s)’ total gross household income from all sources is $48,441 (for 2023) or less. This amount includes income of all residents in the home. The threshold will be increased annually and is based on the annual Consumer Price Index (CPI).
  • Must meet one of the following criteria:
    • A person 65 of age OR 
    • A person 60-64 of age and in receipt of an Allowance under the Old Age Security Act, if widowed, be in receipt of the Spouses Allowance under the Old Age Security OR
