How much does it cost to replace a kitchen countertop in Toronto?

Hey there! I'm Chris, a General Contractor with about 25 years of experience in kitchen renos and home trades. I'll be walking this job with you from start to finish to make sure we capture exactly what you need and get a clear, realistic estimate put together.

Looking at the photo you uploaded, you have a classic, cozy kitchen with what appears to be a white post-form laminate countertop with an integrated cove backsplash, wrapping in a U-shape (or an L-shape with a left return) along the left, back, and right walls. This kind of layout has some great workspace, and replacing the countertop is one of the single best ways to completely transform the space.

To get started, I've done some rough scaling from your photo. I estimate your countertop runs are roughly 15 linear feet in total (about 3 feet on the left, 8 feet along the back sink wall, and 4 feet on the right leading to the wall oven). At a standard 25-inch depth, that's about 31.5 square feet of countertop area.

To help me dial in a realistic cost for your vision, could you help me with a few quick details?

Question: Could you please provide your postal code?

Question: What material would you like for your new countertop?

• Laminate (cost-effective, durable)
• Quartz (highly durable, low maintenance, premium)
• Granite (natural stone, premium)
• Butcher Block (warm wood look, mid-range)
• Solid Surface/ Corian (seamless, mid-to-premium)

Question: Who will be procuring the countertop material?

• I want the contractor to supply it
• I will purchase it (owner-supplied)

Question: Are we keeping your existing sink and faucet, or would you like to replace them? If replacing, who will supply the new fixtures?

• Keep existing sink & faucet (disconnect and reconnect)
• Replace both - I will supply new fixtures (owner-supplied)
• Replace both - contractor to supply new fixtures

Question: Is there an in-counter cooktop or other built-in appliance on the countertop that we need to account for?

• No cooktop or appliances on the counter
• Yes (electric cooktop)
• Yes (gas cooktop)

Question: Do you have approximate measurements of your countertop runs, or would you like us to use our photo-based estimate of about 15 linear feet for now?

• Use the photo-based estimate (~15 lft)
• I will provide my own measurements

Your project estimate

Project summary

Homeowner in Toronto, ON (M4C) wants to replace approximately 15 lft of U-shaped post-form laminate countertop with contractor-supplied Quartz. Existing stainless steel drop-in double sink and faucet will be disconnected and reconnected. No built-in cooktops or in-counter appliances are present. Due to the vintage of the home (pre-1990), a mandatory Ontario regulations asbestos survey of the backsplash area is included prior to demolition.

Estimate range

$4,300 - $6,500 This is a starting ballpark, not a final price.

Estimated work

Item	Details	Range
Hazardous Materials Survey	Perform professional pre-renovation hazardous materials survey and lab analysis for asbestos in the backsplash adhesive/drywall compound, mandatory for pre-1990 homes in Ontario.	$750 - $1,200
Site Protection and Setup	Install temporary floor protection, dust barriers, and cabinet masking to protect finishes in the kitchen work area.	$100 - $200
Sink and Faucet Disconnect	DISCONNECT: Shut off local water supply valves and disconnect plumbing lines, drain assembly, and p-trap for existing drop-in kitchen sink and faucet.	$25 - $45
Demolition and Disposal of Countertop	Carefully remove existing post-form laminate countertop with integrated backsplash. Load, haul, and dispose of debris at an authorized facility.	$250 - $400
Countertop Templating and Cabinet Prep	Template the countertop area, verify level of cabinet bearing surfaces, and install structural support blocking/cleating.	$60 - $90
Quartz Countertop Supply and Install	SUPPLY & INSTALL: Fabricate, deliver, and install premium Quartz countertop, including seam jointing, undermount sink cut-out, and edge profiling.	$2,900 - $4,500
Sink and Faucet Reconnect	RECONNECT: Reinstall and reconnect the existing owner-supplied double-bowl stainless steel sink and deck-mount faucet. Connect to supply lines and drain, and test for leaks.	$100 - $200

Cost summary

Category	Range
Materials	$3,700 - $5,700
Labour	$550 - $850
Total	$4,300 - $6,500

What is included

• Conduct a pre-renovation hazardous materials survey/testing for asbestos on the drywall joint compound and adhesive behind the backsplash (mandatory in ON for pre-1990 homes before substrate disturbance).
• Protect kitchen floor, cabinets, and adjacent finishes.
• Disconnect the existing sink and faucet plumbing.
• Remove the existing laminate countertop and backsplash.
• Template and prepare cabinet tops for new installation.

Item	Trade	Possible range	What would confirm it
Professional hazardous materials abatement for drywall joint compound or adhesive behind backsplash.	General Contractor	$2,000 - $3,000	Mandatory hazardous materials survey (BOP-01) returns positive results for asbestos-containing materials (ACM).
Cabinet framing repair and structural leveling.	General Contractor	$275 - $425	Demolition of existing laminate countertop reveals degraded, unlevel, or structurally inadequate cabinet frames.

That's a great question! I made an educated GC guess based on several clear visual clues in the photo you shared:

• The Cabinets: The flat-panel, wood-grain cabinets with those specific gold-tone wire handles are classic hallmarks of 1970s and 1980s Canadian kitchen design.
• The Countertop Style: The white post-form laminate countertop with that integrated rounded "cove" backsplash was the standard builder finish during that exact same era.
• The Built-in Wall Oven: The style and trim of the white wall oven unit on the right also point directly to a late-20th-century build.

Because these finishes strongly suggest a pre-1990 home, I conservatively flagged it for safety. In Ontario, regulations are strict: they require a hazardous materials survey for any building constructed before 1990 prior to any demolition work. Since removing a glued-on laminate backsplash is highly likely to disturb the drywall or adhesive behind it, a local contractor would be legally required to test those materials first.

However, if your home was actually built in 1990 or later (or if the kitchen walls and drywall were entirely replaced during a newer studs-out rebuild), we can completely remove that Hazardous Materials Survey line item—which would immediately save you about $750 to $1,200 from the estimate!

Does your home happen to be newer than 1990, or has it had a modern drywall overhaul?

It's always great when my GC instincts are on the mark! Since your home was built in 1986, keeping that testing step in the estimate is definitely the right—and legal—move under Ontario guidelines. It protects both you and the crew working in your home.

If the test comes back clean, the crew is good to go with the standard demolition. If it does show any trace of asbestos (which was very common in drywall joint tape, compound, or mastic adhesives of that era), a professional abatement team will just need to safely remove that localized section of drywall before your new Quartz slab is template-fitted and installed.

Since we have a solid, tailored ballpark estimate ready for a contractor to review, you are in a great spot to take the next step.
