You must provide the following information when you submit the Municipal Services Application form:
The City or its contractor shall not be held responsible for additional costs that may arise due to lack of information provided at the time of application.
Where an applicant feels their services are very small in size and scope and does not want to provide detailed site servicing plans, they may opt to proceed with a “blind bid” by submitting only the Municipal Services Application form. In this case, they must however, agree in writing that they are responsible to pay for any cost increase should the underground or other conditions be contrary to initial assumptions made at time of application.
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 four (4) to six (6) weeks from when an application is made. The applicant is required to pay all fees in advance of construction.
Should the scope of work change during construction, the applicant will be required to pay additional costs to cover the scope change before additional work proceeds. The City reserves the right to stop work should the constructed work exceed deposits.
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 actual costs associated with the services delivered.
The City works to turnaround every application and complete the construction of the services within 12–14 weeks from the time the application is made (not including the time required for Toronto Water to complete a technical review where applicable). This timeline may however be extended depending on the time of the year (December to January) or should adverse weather events delay progress on site.
The fees are determined by Toronto City Council annually. See the fees for this year.
Sewer services, may include the following:
Water services, may include the following:
Note: If upgrading the private water service from 13 mm (½ in.) to 19 mm (¾ in.), it is recommended that the City’s side is upgraded to match. Replacing both will provide the most benefit in terms of pressure and flow.
In-person payments will be by appointment only. Please do not visit any location to make a payment without first making an appointment. To arrange an appointment, email twc@toronto.ca or call 416-395-6082. Payment must be made by one individual or company. Payment from more than one payor will not be accepted.
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.
Technical reviews help manage potential impacts to the City’s water and sewer systems and ensure the City’s design requirements are met. Water and/or sewer service connections which are not subject to review and approval by Development Engineering or Engineering Transit Review may require a technical review by Toronto Water, which is subject to applicable fees.
Please submit your application for water and/or sewer service connection or disconnection through the Municipal Services Application for ICI properties. If a technical review is required, Toronto Water staff will contact you regarding next steps on how to submit the supporting documents and make a payment.
A technical review by Toronto Water is required for:
