Renovate a kitchen
A kitchen touches electrical, plumbing, ventilation, and often gas, over a schedule long enough that the price at the end frequently differs from the price at the start. The regulatory picture is less complicated than a basement, but the contractual picture is worse: this is the project where change orders, deposits, and payment schedules cause the most disputes. The single most valuable thing you can do before signing is agree in writing how a change gets priced and approved.
What applies when you renovate a kitchen in Ontario?
In Ontario, this job can involve four bodies: your municipal building department — permit where plumbing is relocated, walls change, or structure is altered; the Electrical Safety Authority (ESA) — notification for new or altered circuits; the Technical Standards and Safety Authority (TSSA) — certified technician for any gas range or cooktop connection; and the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) — designated substance survey where demolition is involved in an older home.

What applies
Permit where plumbing is relocated, walls change, or structure is altered
Who files The contractor.
A cosmetic refit that reuses every existing location often does not need one. Moving a sink usually does. Confirm your scope locally.
Notification for new or altered circuits
Who files The licensed electrical contractor.
Kitchens involve dedicated appliance circuits and counter receptacles with specific requirements. Almost every kitchen renovation triggers this.
Certified technician for any gas range or cooktop connection
Who files The registered contractor.
Applies to moving a gas line for a range, not just installing the appliance.
Designated substance survey where demolition is involved in an older home
Who files The contractor arranges it.
Older kitchens can carry asbestos in flooring and adhesives.

What a complete quote contains
- A written change-order process: how a change is priced, who approves it, and that no change proceeds without written approval
- A payment schedule tied to milestones rather than calendar dates
- Cabinet make and model, or a specification detailed enough to price elsewhere
- Countertop material, edge profile, and who templates it
- Appliance responsibility — who supplies, who installs, who connects gas
- Range hood ventilation: where it exhausts and whether it is ducted outside
- A realistic schedule including cabinet lead time, which is usually the long pole
- Named subtrades for electrical, plumbing, and gas
Questions to ask out loud
How do change orders work, exactly?
Good answer A written process, priced before work proceeds, approved by you.
Worrying answer We'll sort it out as we go. This is where kitchen budgets die.
Is the range hood ducted to the outside?
Good answer Yes, with a route — or a clear explanation of why recirculating is what the space allows.
Worrying answer Doesn't distinguish ducted from recirculating.
What is the cabinet lead time, and when do you order?
Good answer A specific number of weeks, and ordering tied to a deposit milestone.
Worrying answer Vague, which usually means the schedule is fiction.
Who is doing the plumbing and electrical, and are they licensed?
Good answer Names the companies and gives numbers.
Worrying answer Our guys handle everything.
Is the payment schedule tied to milestones or dates?
Good answer Milestones, with a final payment after completion and any inspection.
Worrying answer Calendar dates regardless of progress.
Watch for
high Large deposit with no material order attached to it.
But before you accuse anyone A cabinet order is a legitimate reason for a substantial deposit. Ask what specifically is being ordered and when. Ontario's guidance recommends keeping deposits to no more than 10%.
high No written change-order process.
But before you accuse anyone None on a project this long. This is the number one cause of kitchen disputes.
high Payment schedule front-loaded well ahead of progress.
But before you accuse anyone None. Money should follow work.
medium No estimate written into the contract.
But before you accuse anyone Sometimes the job genuinely is time-and-materials — but understand that without an estimate in the contract, the 10% overrun protection is much harder to rely on.
Currency note
If an estimate is included in your contract, the final price for all goods and services cannot be more than 10% over it unless you agreed to new work or a new price. That protection depends on the estimate being in the contract — not in an email, not in a conversation.
