Fire Hydrant Flow Test in Ontario: Process for Design Teams

Choose the municipal route before ordering a test

For Ontario design teams, Toronto’s route is a certified-contractor test permit, Waterloo’s is an account-based test request, and Richmond Hill’s is a paid application with City-operated hydrants.[1][3][4]

First ask the local authority whether an existing flow record is available and acceptable for the project. Confirm its acceptance criteria and who will supply the final report.[1][3][4] If an acceptable existing record cannot be obtained, use the municipality’s new-test route:

• Toronto — contractor-test permit: Apply for a Fire Hydrant Flow Test Permit. A certified contractor performs the test; City staff inspect and approve the connection and turn the hydrant on and off.[1]
• Waterloo — municipal test request: Developers and contractors request a flow test online by signing in or creating an account.[3]
• Richmond Hill — paid application: Submit an Application For Flow Test at $143 per location. The Water and Waste Water Section reviews it and confirms an appointment; a City Certified Operator operates the hydrants.[4]

Separate mandatory conditions from preparation and location-dependent arrangements:

• Required for Toronto: a certified contractor, application and payment, hydrant locations, applicant-supplied equipment and compliance with the permit’s safety conditions.[1]
• Required to submit Waterloo’s request: sign in or create an account.[3]
• Richmond Hill application conditions: the per-location fee and applicant-supplied test equipment; traffic control and resident or business notification depend on the circumstances.[4]
• Recommended preparation: prepare a location sheet and agree who will deliver a design-acceptable record before commissioning work.

Toronto: plan around the application and testing windows

Toronto’s ordinary application form is open only from 31 March to 31 October, although its testing season runs until 15 November. After 31 October, ordinary applications wait for the next season’s form, which the City says becomes available on 31 March.[1]

Keep these separate windows in the project schedule:

• Ordinary applications: the online form is open from 31 March through 31 October.[1]
• Ordinary testing: tests take place from 15 April through 15 November, with weather above 0°C.[1]
• Off-season requests: permits for 16 November through 14 April are considered case by case under strict requirements. Contact [email protected] to discuss this route.[1]

For an ordinary application, arrange a certified flow-test contractor and apply and pay online at least 10 business days before the requested test date.[1] Have these required details ready:

• The contact’s name, address and telephone number.[1]
• The location of each requested hydrant.[1]

Toronto gives a four-business-day callback, not a commitment to perform the test within four business days. Appointments are available Monday to Friday, between 8 a.m. and 1 p.m.[1] After applying, retain the receipt, permit or permits, and Customer Service Request numbers for follow-up.[1]

Toronto’s permit page does not state a dollar fee; it says City Council approves fees annually and directs applicants to Water Rates and Fees.[1] Check that fee before applying. Payment is by American Express, Visa or Mastercard credit card; payment questions go to [email protected].[1]

To cancel or change the date, contact the staff member who booked the hydrant turn-on/turn-off appointment, or email [email protected], at least 24 hours before the appointment.[1] For a cancelled permit, Toronto refunds the permit fee by cheque within six to eight weeks of cancellation.[1]

Assign Toronto’s testing and safety duties

The applicant must employ a certified flow-test contractor and supply all testing equipment; the City gives a gate valve, pitot and pressure gauge as examples. City staff inspect and approve the contractor’s connection, and only City staff may operate the hydrants.[1]

The applicant must protect public safety while water flows, supply barriers or other protective measures as needed, and keep hoses from crossing roads or sidewalks.[1] The applicant also accepts responsibility for claims arising during hydrant use and agrees to compensate and hold the City harmless.[1]

Staff may refuse an unsafe turn-on, and the City may cancel the permit if public safety is at risk.[1] Confirm proposed hydrant locations and contractor availability before relying on the appointment in the design schedule.[1]

Waterloo: submit an account-based test request

Developers and contractors can request a Waterloo hydrant flow test for building or fire-system design through the City’s online process. Sign in or create an account to submit the request.[3]

Before submitting, send these questions to [email protected]:[3]

• What project information and attachments are required?
• What is the fee, and how is payment arranged?
• When can the test take place, and how long does appointment confirmation take?
• Who takes the measurements, and who is authorised to operate the hydrants?
• Who supplies equipment and any necessary safety measures?
• Who delivers the report, in what format and by what date?
• What terms apply if the appointment changes or is cancelled?

As project preparation—not an additional municipal requirement—obtain these answers before building an assumed appointment or report-delivery date into the design schedule. Keep the City’s response with the request, including the agreed responsibilities and outstanding questions.

Richmond Hill: budget per location and confirm a date

The Water and Waste Water Section reviews the submission, then confirms a suitable date and time.[4] Ask the proposed tester separately about equipment and report-preparation charges rather than assuming the application fee covers those services.

Testing typically takes place from 1 May to 1 November, although the City may adjust that period for climatic conditions.[4] Outside that period, contact the City about availability before planning a test.[4]

The application separates applicant responsibilities from arrangements dependent on the location:

• Equipment: the application calls for the applicant to supply all equipment needed for the test.[4]
• Traffic control, where necessary: it calls for the applicant to prepare and implement a Traffic Control Plan, with traffic-interruption controls complying with Ontario Traffic Manual Book 7.[4]
• Notification, if requested: the City may ask the applicant to notify affected businesses or residents and will specify the extent of notification.[4]

The application says a City Certified Operator operates the hydrants and will operate only one at a time to limit effects on the distribution network.[4] Ask the tester and designer to confirm their proposed approach accommodates that restriction before committing to the appointment.

Ask Richmond Hill for its processing-time commitment and cancellation and refund terms.[4] Obtain those terms, identify who will take the measurements and deliver the report, and confirm whether traffic control or notification applies to the proposed locations.

Map the locations without adding application requirements

Keep required application details separate from information prepared to help the municipality, tester and designer identify the proposed work.

Ask Toronto whether a separate development-site address is required.[1] Ask the municipality whether it requires a map linking the development site, test hydrants and public-main tie-in.[1][3][4]

As recommended preparation, assemble a short location sheet:

• Show the development address and proposed public-main tie-in.
• Mark the requested hydrant locations and identifiers so everyone can confirm which hydrants are intended.
• Where applicable, distinguish the test hydrant from the hydrant proposed for residual-pressure readings.
• Use the same location references in correspondence with the authority, tester and designer.

Ask the authority to confirm the proposed locations and required attachments, and ask the tester to confirm the proposed hydrant arrangement. Do not treat this recommended sheet as a substitute for the municipality’s application or infer Richmond Hill’s application fields from its per-location fee.

Agree on the record the designer needs

Ask the municipality and proposed report supplier who prepares, signs and formally supplies the final record, and confirm the required report template, units, method, acceptance thresholds and validity period.[1][3][4]

Use the following as a recommended confirmation checklist—not an Ontario-wide reporting standard. Resolve it with the proposed report supplier and the authority reviewing the design before commissioning work.

Identify the report supplier and delivery terms

Ask who will prepare, sign and send the record. Confirm what professional certification, if any, the reviewing authority requires, and agree the delivery format and turnaround. Keep hydrant operation, test performance and report preparation separate: Toronto expressly assigns testing to a certified contractor and hydrant operation to City staff.[1]

For an existing record, ask the authority whether it can release the record and whether its location, age and contents are acceptable for this project. Establish what would trigger a new test before deciding that the existing-record route is sufficient.

Confirm identifiers, pressures and observed flow

Ask for the test date, hydrant identifiers and locations, including the residual-pressure hydrant where applicable, and a clear link to the development address and proposed connection.

Agree whether the record will include static pressure, residual pressure and observed flow, with units for each measurement. Waterloo describes its service generally as measuring pressure and flow; the detailed field list should be agreed rather than treated as a promised municipal output.[3]

Ask whether the proposed hydrant arrangement and test method will be acceptable for the design submission. For Richmond Hill, resolve how the approach accommodates the application’s one-hydrant-at-a-time operating restriction.[4] Settle these questions before the appointment rather than waiting to see what the resulting record contains.

Close the request with confirmed responsibilities

Record the agreed route, appointment and deliverable in writing. Use this project checklist to distinguish completed steps from unresolved questions:

• Route: the correct municipal process is selected, and the existing-record versus new-test decision is resolved.
• Locations and documents: hydrant locations are confirmed and required application documents are submitted.
• Payment and timing: the applicable fee and payment are recorded, and the appointment and seasonal eligibility are confirmed.
• Responsibilities: the tester, authorised hydrant operator, equipment supplier and report supplier are identified.
• Conditional arrangements: any traffic-control, protective-measure or notification duties are assigned.
• Deliverable: the report’s contents, delivery date and acceptance for design are agreed with the relevant parties.

Ask whether cancellation, a changed location, project delay or later submission would require another application, renewed permission, another fee or a retest. Confirm any renewal duty, result-validity period or retesting interval with the municipality.[1][3][4]

For Toronto infrastructure alterations requiring City or Ministry of the Environment, Conservation and Parks approval, obtain that separate approval before construction; a flow-test permit is not a substitute.[2]
