On a rural lot it is substantial. The site work alone – drilling a well (about $9,000 to $24,000), installing a septic system (commonly $22,000 to $38,000, and more on hard soil), extending hydro, building a driveway, and clearing and grading – frequently adds $50,000 to $150,000 or more before any footing is poured, and that sits on top of land transfer tax, development charges, permits, surveys, and engineering. A serviced town lot is lighter on site work but still carries development charges, a permit, and the connection from the street, often in the $30,000 to $60,000 range. Because it varies so much from lot to lot, the calculator above breaks the cost into categories so you can enter real quotes and see your own all-in total rather than rely on a single guess.

Development charges are fees that fund the growth-related infrastructure new homes rely on, and in Simcoe County you actually pay three separate bills – one to your township, one to the County of Simcoe, and one for education – all due in full when your building permit is issued. The County-wide portion alone for a single or semi-detached home is about $14,975 in 2026, with roads making up the largest share at roughly $11,013, alongside long-term care, paramedics, waste, transit, and study components. Your township and education charges stack on top, so the real total is higher than the County figure on its own. Rates differ across the County, so confirm all three with your local municipality before you finalize a budget.

Ontario land transfer tax is calculated on a marginal, bracketed basis on the purchase price: 0.5% on the first $55,000, 1% from $55,000 to $250,000, 1.5% from $250,000 to $400,000, 2% from $400,000 to $2,000,000, and 2.5% on the portion above $2,000,000 for one or two single-family residences. The brackets are unchanged for 2026. This calculator applies them automatically when you enter the land price. If the property is in the City of Toronto there is an additional municipal land transfer tax, which the calculator approximates, though Toronto rates are not typically relevant to Simcoe County and Georgian Bay buyers. First-time buyers may qualify for a rebate of up to $4,000, which you should confirm with your lawyer.

Hydro One’s basic connection includes the supply and installation of up to 30 metres of overhead secondary conductor for a 200-amp service, or an equivalent credit toward an underground run. Beyond that 30 metres you pay the incremental cost of the extra conductor, any poles and hardware on your property, and the premium for going underground instead of overhead. On a lot close to the existing line the cost can be modest, but on a long rural setback, through rock or wet ground, or where you want the wire buried, it can climb into the tens of thousands – one Ontario homeowner was quoted around $60,000. Always get a connection quote from Hydro One for your specific lot before you assume a nearby pole means a cheap hookup.

These are the big rural site costs and they add up quickly. A drilled well commonly runs about $9,000 to $24,000, roughly $45 to $115 per foot, with depth and rock pushing it higher, and that is before the pump and pressure system. A septic system typically lands around $22,000 to $38,000 for the raised-bed or pressurized systems many lots need, and a complete project on a difficult site can reach into the sixties. A driveway adds more depending on length and material, with asphalt around $4 to $10 per square foot and concrete roughly $9 to $18, plus clearing, grading, and any rock excavation at $50 to $200 or more per cubic yard. Together these are why a rural lot often needs $50,000 to $150,000 of site work before construction even starts.

Sometimes. Vacant land sold by an individual for personal use is often HST-exempt, while land sold by a builder or developer, or in the course of a business, is usually taxable at 13%. Because it depends on the seller and the circumstances, you should confirm the HST treatment of a specific lot before you assume the quoted price is the final price, and check whether it is plus HST or HST included. The HST toggle in this calculator is a planning aid only. For a fuller explanation of when HST applies and how the new housing rebate can offset part of it, see our guide on HST on vacant land, and confirm the specifics with your accountant.

Because the purchase price is only the front door. A lot that looks like a bargain can carry large hidden costs to make it build-ready: a deep or dry well, an engineered septic system on poor soil, a hydro extension that runs into the tens of thousands, rock excavation, extensive grading, a long driveway, conservation-authority requirements, or studies a tricky site demands. Two lots at the same price can be tens of thousands of dollars apart once you make them buildable, and sometimes the cheaper one ends up costing the most overall. The honest way to compare lots is on all-in build-ready cost, not the sticker price, which is exactly what this calculator is built to help you estimate before you commit to a number.
