Connection or disconnection to the City’s water supply can be requested for:

  • renovation
  • new construction
  • upgrading a shared service (“Y” connection that provides water to two properties) to a single connection

The City does not replace or install water or sewer service connections on private property. This is the property owner’s responsibility.

Information on how to apply for a water/sewer service connection or disconnection (for residential or for industrial, commercial, institutional & multi-residential properties) is found below.

New water and sewer service connections are required:

  • for all new construction
  • when more than 50% of the first story (above grade) of an existing building has been demolished
  • when converting a septic system to the municipal water system

Re-use of an existing connection

Toronto, ON M4S 1A7

Application requirements

You must have the following information with you when you apply:

  • Completed Municipal Services Application (Excel)
    • If someone other than the property owner is applying for the service connection (i.e. contractor), the owner must provide a letter that authorizes the agent to apply for the service(s) on their behalf and states that the owner is responsible for all fees associated with the service(s) provided.
  • Construction of new/infill single family dwellings:
    • Hard copy of the Lot Grading Site Plan approved by Toronto Building. The Plan should indicate the location of the proposed water and sewer service connections, and clearly identify the elevation of the proposed underside of footing and driveway slope.

Fees and sizes

The fees are determined by Toronto City Council annually. See the fees for this year.

For sewer services, there are fees for:

  • Installing new sewer service connections up to 150 mm (6 in.)
  • Disconnecting sewer service connections
  • Re-use of residential sewer service connection – subject to approval

For water services, there are fees for:

  • Installing 19 mm (¾ in.) new residential water service and meter
  • Installing 25 mm (1 in.) new residential water service and meter
  • Disconnecting any residential water service less than or equal to 25 mm
  • Re-use of residential water service 19 mm to 25 mm – subject to approval

Note: If upgrading the private water service from ½ in. to ¾ in. (19 mm), it is recommended that the City’s side is updated to match. Replacing both will provide the most benefit in terms of pressure and flow.

Applicants requesting a water service greater than 25 mm are required to follow the application process for industrial, commercial, institutional (ICI) and multi-unit residential properties.

  • Certified cheque (made payable to “Treasurer, City of Toronto”)
  • Bank draft or money order (made payable to “Treasurer, City of Toronto”)

Installation and water turn-on

Installation will occur within 12 weeks of receiving payment. Applicants must contact their assigned City Contractor to schedule and confirm the location of the water and sewer service connections. Applicants will be provided with the contractor’s contact information at the time of application and payment.

Once the new water service has been installed, a request must be submitted to have the water turned back on.

  • Fifteen (15) copies of the Site Servicing Plan will be required after the preliminary review by Toronto Water.

Fees and sizes

Connections will be sized according to the intended use, as defined by the approved application.

Toronto Water estimates the costs by tendering the job to a roster of approved City of Toronto contractors. The costs will be communicated to the applicant within approximately six to eight weeks of application. The applicant is required to pay all fees in advance of construction.

Once the work is complete, the actual costs will be determined. Should the actual costs be less than the estimate, the payer will be issued a refund. If the costs are greater, the applicant will be sent an invoice. The applicant is responsible for all costs associated with the services delivered.

Method of payment

  • Certified cheque (made payable to “Treasurer, City of Toronto”)
  • Bank draft or money order (made payable to “Treasurer, City of Toronto”)
  • Credit card: American Express, Visa and MasterCard
    • The cardholder must be present
  • Debit card

Note: Payment must be made by one “payor.” Payment from more than one individual or company will not be accepted.

Installation and water turn-on

The installation date is coordinated with the applicant after the City has established the fee for the work and the applicant has paid for the service installation. The City and contractor will arrange for a pre-construction inspection and site meeting with the applicant to finalize the line and grade of the services to be installed.

Once the new water service has been installed, a request must be submitted to have the water turned back on.
