## What should I do first when a pipe bursts in the building?

Close the building's main water valve, then call [(416) 888-1371](tel:+14168881371). In Toronto the main valve is typically on the foundation wall where the water pipe enters, just before the meter, and if it will not close, 311 can shut the water off at the property line for a fee [(City of Toronto)](https://www.toronto.ca/services-payments/water-environment/your-water-pipes-meter/water-related-help-advice/pipe-leak-or-burst/). In Mississauga, Markham and Ajax the region or town does it; their numbers are on each [city page](https://www.jackmanmechanical.com/areas/).

## What kind of commercial plumbing is it?

**Commercial plumbing work**

| Work | Examples | How to send it |
| --- | --- | --- |
| Service calls | A leak, a blocked drain, a fixture or shutoff that has failed | Call for an emergency; otherwise "A repair" on the form, with photos |
| Fit-outs and renovations | New washrooms, kitchens and sinks, moved fixtures, new supply and drain piping | "A quote to replace or install", with photos and any drawings |
| New construction | Supply and drain piping, roughed in before the walls close and the floors are poured | "A quote to replace or install", with the drawings and the schedule |

## Which permits apply to commercial plumbing in Toronto?

Toronto Building issues stand-alone plumbing permits. Its 2026 fees include $30.94 for each plumbing fixture in a building other than a single-family house, and $92.79 for each backflow prevention device [(City of Toronto)](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-application-guides/standalone-plumbing-mechanical-and-drains/standalone-plumbing-and-drain-permits/). The [permits guide](https://www.jackmanmechanical.com/guides/plumbing-heating-permits-toronto/) has the full table.
