Grease Interceptor Installation and Replacement in Toronto
Also called: new interceptor, trap replacement, sizing. 6 approved companies listed, in alphabetical order.
The approval this page requires
Installing or replacing a grease interceptor needs a building permit, and the work must follow the Ontario Building Code, as the City's installation page explains. Under Toronto Municipal Code Chapter 545, a business that contracts or repairs plumbing installations, or advertises itself as a plumbing contractor, must hold a Plumbing Contractor licence.
To be listed here, a company must hold an active City of Toronto Plumbing Contractor (or Plumbing & Heating Contractor) licence in the City's published business licence data, and its own website must offer grease trap or interceptor installation. Each row shows the licence number and the day we checked it.

When a new interceptor is on the table
Most kitchens replace an interceptor for one of four reasons: the old one has corroded or cracked, a renovation or new menu has outgrown it, a new tenant is fitting out a space, or the City has told them to. The City can require a new interceptor if the existing one is harming the sewer system, or after a significant change such as an expansion, a new business on the premises or a new building (installation rules).
If you're taking over a former restaurant, ask the landlord for the existing unit's make, model and drawings before you sign. Retrofitting a unit into a finished floor costs far more than planning one into a fit-out.
Choosing the type
- Point-of-source hydromechanical unit: The usual choice for a single kitchen. It sits under the sink or in the floor and must meet CSA B481.1:22 and be sized correctly.
- Grease recovery device: Skims grease into a separate container automatically. It suits kitchens where a pump truck can't easily reach the unit, but someone has to empty it every day.
- Gravity interceptor: A large in-ground tank for big kitchens, institutions and food processors, sized under the Ontario Building Code. It usually means excavation outside the building.
- Solids interceptor: Often added ahead of the grease interceptor where food solids are heavy. Grinders and peelers may only discharge through one.
Sizing depends on your fixtures and flow, which is exactly what a licensed contractor's drawings are for.
What the job involves in Toronto
- A site visit to count fixtures, check where the drains run and decide where the unit can sit with clear access for servicing.
- A building permit application. Ask whether your contractor handles it and whether the fee is in the quote.
- Installation to the Ontario Building Code, with the inlet and outlet labelled to show the direction of flow.
- Inspection, then the first pump-out booked four weeks out.
Where it goes matters for years
The City requires the interceptor to be easily accessible for maintenance and inspection. In practice that means a lid you can open without moving a cooler, room to lift out the baffles, and, for in-ground units outside, a spot that won't be under a snowbank or a parked delivery van every winter. A unit that's hard to reach gets serviced late, and late servicing is what the City fines.
Questions to ask an installer
- What is your City of Toronto Plumbing Contractor licence number?
- Will you pull the building permit, and is the inspection included?
- Which fixtures will you connect, and why? (Hand sinks, toilets and urinals must not be connected.)
- Will the unit's CSA markings be visible once installed? If not, will you give me the manufacturer and installation drawings to keep on site?
- What capacity is the unit rated for, and what pumping schedule do you expect?
