Hiring a renovation contractor in Ontario

No. Renovation contractors are not licensed in Ontario - but the sub-trades they hire may be, and the permits are the real accountability mechanism.

Typical costs

Bathroom renovation: $15,000 – $40,000
Kitchen renovation: $25,000 – $80,000
Basement finishing, per square foot: $40 – $90
Legal secondary suite conversion: $60,000 – $150,000

Full hiring guide

You may not need to hire

A few jobs in this trade are within reach of a homeowner. These guides say how, and where to stop.

Working in this area

Two-tier municipal structure
Building permits come from the City, while some servicing and road-related approvals sit with the Region. Confirm who is issuing what.
Century homes downtown
Older core neighbourhoods carry the usual pre-war issues: original wiring, plaster walls, limited insulation.

More about hiring in Waterloo

Why a region, not just your town

Contractors work across municipal boundaries. Listing only businesses registered in one town would hide plenty that serve it. How we rank these.

What renovation work costs in Ontario

Renovation quotes are only comparable when the specification is identical, which it almost never is. Two bathroom quotes $12,000 apart usually differ on tile, fixtures, whether plumbing is being moved, and how much contingency is built in. Ask every contractor to quote the same written specification, or you are comparing nothing.

Job	Typical range
Bathroom renovationMoving plumbing, and the tile specification, drive most of the variance.	$15,000 – $40,000
Kitchen renovationCabinetry is typically 40 to 50 percent of the total.	$25,000 – $80,000
Basement finishing, per square footA bathroom, egress window or legal suite requirements push well past this.	$40 – $90
Legal secondary suite conversionFire separation, egress and parking requirements are what cost the money.	$60,000 – $150,000
Whole-home renovation, per square footA gut renovation approaches new-build cost per foot.	$150 – $350
Addition, per square footFoundation, roof tie-in and servicing make additions expensive per foot.	$300 – $550

Planning estimates for Ontario, not quotes. Always get written quotes against the same written specification.

Questions to ask before you hire

Will you pull the building permit in your company name?
Can I see the written scope, and does it list specific products and models rather than allowances?
What is the payment schedule, and is it tied to milestones rather than dates?
How are change orders priced and approved - in writing, before the work happens?
Who are your electrician and plumber, and can I verify their licences?
What is your contingency assumption, and what happens if you open a wall and find a problem?
How many projects will you be running simultaneously while mine is open?
Can I speak to two customers whose projects finished more than a year ago?

Warning signs

A large up-front deposit. Materials deposits are normal; a third or more of the contract value before work starts is not.
Any suggestion that you pull the permit yourself, or that the job does not need one when it clearly does.
A quote on a single page for a $40,000 project.
Verbal change orders. "We'll sort it out at the end" reliably means a dispute at the end.
