How much does a general contractor cost in Whitby?
A mid-range Durham Region kitchen costs $40,000 to $70,000 in 2026, says Wilworks Renovations, a firm not ranked here. Ramsauer Renovations, an Oshawa firm, puts a full bathroom at about $10,750 to $22,500 and a basement at $27,000 to $90,000 or more. Most general contractors build their fee into those totals.
| Job | Typical cost (CAD) | Source |
|---|---|---|
| Kitchen refresh (doors, fronts, counters) | $15,000 to $30,000 | Wilworks Renovations |
| Kitchen, mid-range | $40,000 to $70,000 | Wilworks Renovations |
| Kitchen, full gut | $65,000 to $110,000+ | Wilworks Renovations |
| Full bathroom | About $10,750 to $22,500 | Ramsauer Renovations |
| Finished basement | $27,000 to $90,000+ | Ramsauer Renovations |
| Whitby house alteration permit | $10.65 per m², $305 minimum | Town of Whitby |
| Whitby addition permit | $22.37 per m² | Town of Whitby |
Scope drives the price more than the fee does. Wilworks says removing a load-bearing wall is a common request in older Whitby homes, and it adds a beam, posts and footings that must be engineered and permitted. Ramsauer puts decks and fences from about $4,500, so outdoor jobs start lower.

How do you choose a general contractor in Whitby?
To choose a Whitby general contractor, check its WSIB clearance and liability cover. Ask who pulls each permit, then compare written quotes for the same scope. Ontario law says any home reno contract worth more than $50 must be in writing. The province also suggests a deposit of no more than 10% of the price.
- Check the licence. A general contractor hires the trades, and Ontario says no one can run an electrical contracting business without an ESA licence. Check the electrician on your job in ESA's Contractor Locator.
- Confirm WSIB clearance. Ask for the company’s WSIB account number and confirm a current clearance on WSIB’s free eClearance lookup.
- Ask for proof of liability insurance. A certificate of commercial general liability insurance should name the company that will do the work.
- Ask about city licences and permits. Ask Whitby whether the job needs a municipal licence or building permit before work starts.
- Get it in writing. Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree (Ontario consumer protection rules).
- Keep the deposit small. Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.
Whitby adds the greater of $100 or 25% of the fee when work starts before a permit application. Name the permit holder in the contract. Ontario also says, “The final price for all goods and services cannot be more than 10% over the original estimate unless you have agreed to new work or a new price.”
