Buying land in Ontario, whether to build a house, hold as an investment or develop later, depends on four local questions: what the zoning and Official Plan allow, whether the lot can be severed, what the building permit requires and, off municipal services, whether a septic system and well can be approved. Those four questions are the sections below. GST/HST, closing costs and the checks that apply in every province sit on the Canada-wide land guide, with separate pages for Quebec, BC and Alberta, all part of our property types guides.
Types of land in Ontario
| Type | Description | Price Range | Key Considerations |
|---|---|---|---|
| Serviced urban lot | Municipal water/sewer, paved road | $100K–$800K+ | Ready to build; zoning and building permits required |
| Serviced suburban lot | New subdivision, all services | $150K–$600K+ | Often purchased from a builder as part of a new-build package |
| Rural residential lot | Cleared, some services (may need well/septic) | $50K–$300K | Check servicing status carefully |
| Raw rural acreage | Unserviced, may have no road access | $30K–$200K+ | Significant servicing costs; may need severance |
| Agricultural land | Farmland zoned agricultural | $10K–$30K+ per acre | Strict zoning restrictions; limited residential building |
| Waterfront lot | Lake or river frontage | $100K–$1M+ | Environmental and setback rules |
| Infill lot | Vacant lot in an established urban neighbourhood | $200K–$1M+ | May involve demolition; check zoning for permitted density |
Zoning and planning
Key zoning terms
| Term | Description |
|---|---|
| Permitted use | What the zoning allows (residential, commercial, agricultural, mixed-use) |
| Minimum lot size | Smallest lot area allowed in that zone |
| Minimum frontage | Minimum width of the lot at the street line |
| Setbacks | Required distance from each lot line (front, rear, side) to any structure |
| Lot coverage | Maximum percentage of the lot that can be covered by buildings |
| Height restriction | Maximum building height (in metres or storeys) |
| Accessory structures | Rules for garages, sheds and garden suites |
Before you buy: planning checklist
| Item | How to Check |
|---|---|
| Zoning | Contact the municipality’s planning department or search their online zoning maps |
| Official Plan designation | Confirm the land is designated for your intended use |
| Severance history | Check if the lot was recently severed, since conditions may apply |
| Conservation authority | Check if the lot falls within a conservation authority regulated area (floodplain, wetland, slope) |
| Environmental constraints | Endangered species habitat, significant woodlands, species at risk |
| Minimum Distance Separation (MDS) | Near agricultural operations, MDS formulas restrict how close you can build |
| Road allowance | Confirm the lot has legal access to a public road |
| Greenbelt | Check whether the land is inside Ontario’s Greenbelt, where development is restricted |
Lot severance (consent to sever)
The process
| Step | Details |
|---|---|
| 1. Pre-consultation | Meet with the municipality’s planning department to discuss feasibility |
| 2. Application | Submit to the local consent authority (a Committee of Adjustment or Land Division Committee in many municipalities) |
| 3. Required documents | Plot plan, planning justification, servicing assessment |
| 4. Public notice | Neighbours and agencies are notified and can comment or object |
| 5. Hearing | The committee hears the application; you (or your planner) present |
| 6. Decision | Approve (with or without conditions), refuse, or defer |
| 7. Conditions | Typical conditions: road widening, parkland dedication, municipal fees, replanning |
| 8. Appeal | Decisions can be appealed to the Ontario Land Tribunal (OLT) |
Severance costs
| Cost | Amount |
|---|---|
| Application fee | $1,500–$5,000+ (varies by municipality) |
| Planning consultant | $3,000–$8,000 |
| Survey | $2,000–$5,000 |
| Parkland dedication / cash-in-lieu | Up to 5% of land value or equivalent cash |
| Road widening / municipal requirements | Varies |
| Legal fees | $1,500–$3,000 |
| Total | $10,000–$25,000+ |
Financing vacant land in Ontario
Some major banks lend on serviced lots, while unserviced rural land usually needs a larger down payment and goes more often to credit unions and private lenders; cash, a home equity line on an existing home and a vendor take-back are the other common routes. A lot that still needs a severance, or a septic approval, is harder to finance until those are in place. Our vacant land mortgage guide compares land-loan terms, and construction loans explains how a build is paid for in stages.
Building on your land
The building permit process in Ontario
| Step | Timeline | Details |
|---|---|---|
| 1. Confirm zoning compliance | 1–4 weeks | Verify your plans meet zoning requirements |
| 2. Site plan / minor variance (if needed) | 2–6 months | Required if your plans do not fully conform |
| 3. Design and engineering | 2–6 months | Architect/designer prepares drawings; engineer provides structural, septic, etc. |
| 4. Submit building permit application | 1–4 weeks | Plans, engineering, septic design (if applicable) |
| 5. Permit review | 4–12 weeks | Municipality reviews for Ontario Building Code compliance |
| 6. Permit issuance | After approval | Pay permit fees and development charges |
| 7. Build | 10–18 months | Construction per approved plans |
| 8. Inspections | During construction | Municipal inspections at key stages (footings, framing, plumbing, electrical, final) |
| 9. Occupancy permit | After final inspection | Required before you can move in |

Septic system requirements
| Factor | Details |
|---|---|
| When needed | Any property not connected to municipal sewer |
| Design | Designed by a qualified designer and approved by the municipality or health unit |
| Soil test (percolation test) | Determines soil absorption capacity; buyers often make the purchase conditional on it |
| Types | Conventional (bed/trench), raised bed, tertiary treatment (for challenging soils) |
| Cost | $15,000–$40,000+ depending on type and soil conditions |
| Setbacks | Minimum distances from well, property lines, water bodies |
| Maintenance | Pumping every 2–3 years ($300–$500) |
Well requirements
| Factor | Details |
|---|---|
| When needed | Any property not connected to municipal water |
| Type | Drilled well (most common), dug well, or bored well |
| Cost | $5,000–$15,000 for a drilled well |
| Flow rate | Minimum 3 imperial gallons per minute is a common guideline for a single-family home |
| Water quality testing | Test for bacteria, nitrates, minerals |
| Setbacks | Minimum distances from septic system, property lines |
| Risk | There is no guarantee of finding enough water of good quality |
Rural vs urban land
| Factor | Urban / Suburban | Rural |
|---|---|---|
| Price | Priced per lot ($200K–$1M+ per lot) | Priced per acre ($5K–$50K per acre) |
| Servicing | Municipal water/sewer available | Well and septic required |
| Road access | Paved, municipal maintenance | May be seasonal, private, or unmaintained |
| Hydro | At the lot line | May need to extend ($10K–$50K+) |
| Financing | More lenders lend on serviced lots | Fewer lender options |
| Zoning | Residential zones, generally clear | Agricultural, rural residential, more restrictions |
| Development charges | $20,000–$100,000+ for new builds | Lower or none |
| Building timeline | Shorter (services available) | Longer (servicing adds time and cost) |
Due diligence checklist for buying land
- Confirm zoning and permitted uses
- Verify the lot has legal road access (frontage on a public road)
- Check for easements, rights-of-way, or encumbrances (title search)
- Order a survey or review an existing survey
- Check conservation authority mapping (floodplain, wetland, hazard lands)
- Perform a soil test / percolation test (if septic is needed)
- Confirm hydro availability and connection cost
- Review the municipality’s Official Plan for the area
- Ask about development charges and parkland fees
- Check for restrictive covenants or subdivision agreements
- Confirm the lot was not previously used for industrial/commercial purposes (contamination risk)
- Discuss your building plans with the municipality’s building department before closing
- Budget for Ontario’s land transfer tax
