The quote says 'permits included.' Lovely. Then the electrician asks for an ESA notification number, and you discover the paperwork has more than one front door. An Ontario kitchen can involve the municipality, ESA and TSSA-regulated gas work at the same time. Here is what each covers, who should handle it and what you should have in your house file when the crew leaves.

Who handles each part of the work

LaneTypical scopeWho handles it

TSSA fuels rulesGas piping, fuel-burning appliances, certified technicians and registered contractorsTSSA-regulated fuels contractor and technician

Ontario's building permit guide explains the municipal lane. ESA publishes its notification and inspection process. TSSA explains how to verify a registered fuels contractor. These systems can overlap on the same room without becoming interchangeable.

A kitchen example

On a kitchen opening we coordinated, the owner had the municipal permit printed beside the fridge and assumed that covered everyone. At the pre-start meeting, we added the electrical contractor's notification number to the job sheet and put the gas technician's visit on the calendar. The drywaller needed the release dates, too. Nobody wanted to reopen a freshly boarded ceiling because one approval was still outstanding. Removing a bearing wall, moving a sink, adding circuits and relocating a gas range can involve separate reviews; the hood may add mechanical work. Our kitchen permit guide walks through the sequence.

A basement example

Add a bedroom, bathroom, receptacles, lighting, and a gas fireplace. The room use, exits, fire safety, plumbing, and HVAC can sit in the municipal permit package. Electrical work has its own ESA process. Gas work stays with the registered fuels contractor. Start with the basement permit guide, especially before anyone closes the ceiling.

Records worth keeping

  • Issued building permit, approved drawings, revisions, and municipal inspection results.
  • ESA notification information and Certificate of Acceptance when issued.
  • Gas contractor identity, technician information, appliance manuals, commissioning, and correction records.
  • Photos of concealed work plus invoices and warranties.

Once you know who handles each approval, the next question is when the work can move on. The renovation inspection guide explains what needs to stay visible before walls and ceilings close. Put those stages on the same calendar as the trades; separate paperwork should not mean separate plans.
