How Much Does It Cost to Flip a House in Ontario? (2026 Full Breakdown)

Here’s a complete, line-by-line breakdown of every cost you’ll face on an Ontario flip. Three scenarios — Low, Mid, and High — cover the range from a cosmetic flip in Windsor to a full gut renovation in Toronto. These are additional costs on top of the purchase price.

Ontario Land Transfer Tax: The Full Bracket System

Ontario’s Land Transfer Tax is calculated on a sliding bracket system — not a flat percentage. The more you pay for the property, the higher the effective rate. Every Ontario flip purchase triggers this tax on closing day, paid by the buyer.

Toronto Municipal Land Transfer Tax (MLTT)

If you’re buying in Toronto, the City of Toronto charges a second, identically-structured Land Transfer Tax on top of the provincial rate. The brackets mirror the provincial system exactly:

On an $780,000 Toronto purchase, you pay the Ontario LTT and the Toronto MLTT simultaneously — a combined LTT cost approaching $22,000–$24,000 before you’ve touched a wall. No other major Ontario city doubles this tax. It is the single most cited reason experienced Ontario investors target Hamilton, Kitchener, and London over Toronto for flip deals: the same purchase price in Hamilton saves you the entire MLTT amount as pure additional margin.

Beyond LTT, budget for legal fees ($1,500–$2,500 for purchase-side), a home inspection ($500–$700), and title insurance ($250–$500). Skipping the home inspection on a flip property is one of the most common — and most costly — mistakes Ontario investors make.

Renovation Costs: Ontario Contractor Rates by City

Renovation is where Ontario flips make or lose money. It’s also the hardest cost to pin down before you own the property. Here’s how the ranges break down by scope:

• Cosmetic flip ($25,000–$45,000): New flooring, paint, kitchen cabinet refacing, updated fixtures. No structural or mechanical work. Quick turnaround — typically 6–10 weeks.
• Mid-range renovation ($65,000–$100,000): Full kitchen and bath replacement, electrical panel upgrade, new HVAC, possibly windows. 12–18 week timeline.
• Full gut renovation ($120,000–$200,000+): Down to the studs. New plumbing, electrical, HVAC, insulation, drywall, everything. 5–6 months minimum.

Labour rates in Ontario vary significantly by market. GTA contractors command a 25–40% premium over the provincial average due to higher overhead, stronger demand, and a persistent skilled trades shortage. Budget accordingly based on where your flip is:

• GTA (Toronto and inner suburbs): General labour $85–$115/hr; licensed electricians $110–$145/hr; plumbers $100–$140/hr. GC markup typically 15–20% on top of subtrades.
• Ottawa: General labour $68–$88/hr; electricians $95–$125/hr; plumbers $90–$120/hr. OREB-market flips benefit from a strong resale market but higher contractor costs than Hamilton.
• Hamilton / Kitchener-Waterloo: General labour $65–$85/hr; electricians $85–$110/hr; plumbers $80–$105/hr. Best labour-cost-to-ARV ratio in Ontario for mid-range renovations.
• London / Windsor: General labour $55–$75/hr; electricians $75–$100/hr; plumbers $70–$95/hr. Lowest contractor costs in the province; renovation ROI is strong on older housing stock.

The 20% contingency rule exists because renovation budgets in Ontario almost always run over. Material costs rose 18–22% between 2021 and 2024. Always budget contingency as a hard line item, not an optional reserve.

The HST warning most flippers miss: If your renovation removes or replaces more than 90% of the interior living space — excluding foundation, exterior walls, and roof — CRA classifies it as a “substantial renovation.” That triggers HST (13%) on the full sale price. On a $700,000 sale, that’s $91,000 in HST. Full gut renovations can hit this threshold. Mid-range renos usually don’t — but always confirm with a tax accountant before you start. See the full HST rules below, including the separate rules for new builds.

Carrying Costs: The Silent Profit Killer

Carrying costs are the expenses you pay every month you own the property — whether workers show up or not. In Ontario, they’re higher than in most other provinces because purchase prices are higher. More property value means a bigger mortgage, higher property tax, and more insurance.

On a $580,000 purchase with 20% down, you’re carrying a $464,000 mortgage. At a 6% mortgage rate — reflecting lender spreads on investment properties — monthly principal and interest runs approximately $2,000–$2,100. Over a 7-month renovation and listing period, that’s roughly $14,000 in mortgage payments alone.

Add property tax (~$415/month in Hamilton on a $580K property), insurance (~$130/month for a vacant renovation property), and utilities (~$230/month to keep the heat on and prevent damage). Total carrying costs on a mid-range Ontario flip: $19,400 over 7 months.

Every extra month costs you $2,500–$3,000. Renovation delays are the most common cause of margin erosion on Ontario flips. Slow contractor timelines, permit delays, and material back-orders can push a planned 4-month reno to 6 months — adding $5,000–$6,000 in carrying costs you didn’t budget for.

Selling Costs: Ontario Realtor Commission Norms

Ontario realtor commissions are not regulated — they are negotiable — but market norms have remained stable for years. In both the TRREB (Toronto Regional Real Estate Board) and OREB (Ottawa Real Estate Board) markets, the typical structure is a total commission of 4.5–5% of the sale price, split between the listing agent (2–2.5%) and the buyer’s agent (2–2.5%). On a $750,000 sale at 4.5%, that’s $33,750 in commission — before HST.

Add 13% HST on the commission (realtor services are a taxable supply in Ontario) and the true cost is $38,138 on a $750,000 sale. That number surprises a lot of first-time flippers who forgot HST applies to the commission itself, not just the sale price.

Staging is worth budgeting as a real cost, not an optional extra. A staged property in Ontario typically sells for 1–3% more and spends fewer days on market, according to the Ontario Real Estate Association. Budget $2,000–$5,000 depending on property size and market. Factor in $1,000–$1,500 for legal fees on the sale side, plus $1,000–$4,000 for pre-listing repairs — the small fixes buyers use to negotiate price reductions. Total selling costs on a $750,000 Ontario flip: $36,000–$44,000 before tax.

Tax Costs: CRA Anti-Flipping Rule, Ontario Provincial Rate, and HST on New Builds

This is the section most online guides get wrong or skip entirely. In Canada, how you’re taxed on a flip depends on hold period, renovation scope, and whether the property was resale or new construction — all of which have Ontario-specific implications.

Sold within 12 months → CRA’s Residential Property Flipping Rule applies. Under this rule, effective January 1, 2023, any property sold within 12 months of purchase is automatically treated as business income — not a capital gain. You cannot use the principal residence exemption. Read the full rule on the CRA Residential Property Flipping Rule page.

Sold after 12 months → Capital gains treatment. Only 50% of your profit gets included in taxable income. The same $100,000 profit triggers approximately $23,080 in combined tax — saving you roughly $23,000 compared to business income treatment. The math alone justifies planning your hold period carefully.

Ontario’s provincial layer — why the combined rate matters. The CRA rule determines income characterization (business income vs. capital gain). Ontario provincial income tax then applies on top of the federal rate. At Ontario’s top combined marginal rate:

• Federal income tax: up to 33%
• Ontario provincial income tax: 13.16%
• Combined: 46.16% on business income at the top bracket

A $100,000 flip profit taxed as business income in Ontario costs $46,160 in combined federal+provincial tax. The same $100,000 taxed as a capital gain (50% inclusion) costs approximately $23,080. Ontario’s provincial rate is one of the highest in Canada — second only to Nova Scotia — which makes the 12-month threshold particularly important for Ontario flippers compared to investors in lower-tax provinces.

HST on New Builds in Ontario: A Separate Exposure

The HST exposure discussed above (“substantial renovation” triggering HST on resale) is separate from the rules governing new residential construction. If you are flipping a newly built home — or a property where you acted as the “builder” under the federal Excise Tax Act — Ontario’s 13% HST applies to the full sale price from the first dollar.

Three scenarios trigger builder HST status in Ontario:

1. New build for sale: You purchase a lot, construct a home, and sell it. You are the builder; 13% HST applies to the sale price.
2. Substantial renovation: As described above — >90% of interior living space replaced. CRA treats this as equivalent to new construction for HST purposes.
3. Self-supply rule: If you build or substantially renovate and then occupy the property rather than selling it immediately, CRA may assess HST on the fair market value at the time of occupancy. Relevant if you move in after a full gut reno and later sell.

On a $750,000 new build sale, 13% HST = $97,500. The Ontario New Housing Rebate can partially offset this: 75% of the Ontario portion (8%) is rebated for homes sold as a primary residence to an end buyer, for homes priced at or below $400,000 (phasing out between $400K and $500K). Above $500,000, no Ontario portion rebate applies. The federal GST New Housing Rebate similarly phases out between $350,000 and $450,000. At $750,000 — where most Ontario flips transact — neither rebate applies in full. The full HST burden falls on the transaction. Always confirm HST status with a tax accountant before beginning any project that could cross the substantial renovation threshold.

Which Ontario Cities Give Flippers the Best Margin?

The same renovation-driven value uplift that drives flip profits exists across Ontario — but LTT exposure, contractor rates, and purchase price levels create significant differences in achievable margin between cities. Toronto flips are viable, but they require more capital and carry higher structural costs than mid-market Ontario cities.

LTT figures are approximate; use the LTT Calculator for exact amounts. Gross margin = (ARV − purchase price − all non-purchase costs) ÷ ARV. Ranges reflect 2026 market conditions in mid-range price segments.

Hamilton and London consistently produce the strongest risk-adjusted margins for Ontario flippers in 2026: lower purchase prices mean less capital at risk, the provincial LTT is the same as everywhere else (no MLTT), contractor rates are 25–35% below GTA, and the older housing stock in both markets provides reliable renovation-driven value uplift. Toronto flips with thin margins get squeezed further by the MLTT — an $8,000–$12,000 cost that simply doesn’t exist in any other Ontario market.

How to Reduce Your Flip Costs in Ontario

You can’t eliminate these costs. But you can reduce them significantly with the right decisions before you make an offer.

1. Target mid-range Ontario markets. Hamilton, London, Barrie, and Kitchener all offer lower Land Transfer Tax, lower contractor rates, and faster reno-to-sale timelines than Toronto. A $550,000 property in Hamilton produces the same renovation-driven value uplift potential as a Toronto property at $100K–$200K more — with less capital at risk and no MLTT.
2. Keep renovation scope below the substantial renovation threshold. Cosmetic and mid-range renovations don’t trigger HST on the sale. Full gut renovations can. If your reno is trending toward 90% of interior replacement, talk to a tax accountant before proceeding. Slightly reducing scope can save $50,000–$90,000 in HST on a $700K+ property.
3. Plan for a 12-month hold if your timeline allows it. The difference between business income tax and capital gains tax on a $100,000 profit in Ontario is approximately $23,000. If your reno finishes at month 8–9, listing fast and selling in month 10–11 costs you $23,000 more than waiting until month 13.
4. Get three contractor quotes. Renovation cost variance in Ontario is 20–40% between quotes on the same scope of work. Three quotes is the minimum on any project over $30,000.
5. Model all costs before you make an offer. Most flippers underestimate total non-purchase costs by 15–25%. Use a calculator that includes LTT, carrying costs, realtor fees, and tax — not just reno budget vs. ARV.

Bottom Line

Flipping a house in Ontario costs far more than the renovation budget. On a mid-range Hamilton flip, you’re looking at $167,000 in non-purchase costs before a dollar of tax — and CRA’s anti-flipping rule can take another $46,000 at Ontario’s combined 46.16% rate if you sell too fast. Add Toronto’s double Land Transfer Tax or an HST-triggering substantial renovation, and a flip that looked profitable on paper can post a loss on closing day. The flippers who win in Ontario are the ones who model every cost — LTT bracket by bracket, contractor rate by city, hold period vs. tax treatment — before they make an offer.

Start with the numbers: run your flip through the House Flipping Calculator — it covers LTT, carrying costs, realtor fees, and projected profit in one place. If you want to stress-test the tax side, use the House Flip Tax Calculator to compare business income vs. capital gains treatment on your specific numbers.
