Buying 100 acres in Ottawa: practical guidance for land, homes, and investment
When buyers type “100 acres Ottawa” (sometimes as 100 akers, 100 acers, 100 actes, 100 achres, 100 acr, or even “100 acres.”), they're usually weighing a few scenarios at once: a rural homestead, a 100 acre house with outbuildings, or a long-term land hold. Ottawa's rural area stretches far beyond the urban boundary—think Carp, Dunrobin, Osgoode, Cumberland, and the valley communities—so due diligence differs from an in-town purchase. Below is a concise, province-aware roadmap to help you evaluate a 100 acre property or land for sale over 100 acres in and around the National Capital Region.
Land use and zoning fundamentals for 100 acres Ottawa
Ottawa relies on the City of Ottawa Official Plan and Zoning By-law 2008-250. On 100-acre parcels you'll frequently encounter Rural Countryside (RU) and Agricultural (AG) zones, along with Environmental Protection (EP), floodplain overlays along the Ottawa River, mineral aggregate designations, or wellhead/source water protection areas. Each affects how you can build, sever, and use the land.
- RU vs. AG: RU generally allows a dwelling and rural uses; AG prioritizes farming and may limit non-farm residential, additional dwellings, and severances. OMAFRA's Minimum Distance Separation (MDS) rules can restrict siting a home near livestock barns or manure storage.
- Severances: Rural lot creation is tightly controlled. Even on 100 acres, the Committee of Adjustment may grant only limited consents, and prior severance history matters. Confirm severance potential with City planning staff before valuing land on subdivision potential.
- Conservation authority approvals: The Rideau Valley, Mississippi Valley, or South Nation Conservation may require permits for works near wetlands, floodplains, or watercourses. If a tract includes Provincially Significant Wetland or hazard lands, development can be heavily constrained.
Because zoning and overlays vary parcel by parcel, obtain a zoning compliance report, review mapping with a planner, and check for rights-of-way, unopened road allowances, or utility corridors on title.
Access, services, and site work: what a 100 acre house needs
Rural 100-acre properties commonly rely on well and septic. Lenders and insurers pay close attention to both.
- Wells: Ask for well logs and a recent potability test. In some pockets of limestone, iron/sulphur treatment may be needed. Where aquifer yields are uncertain, a drilling allowance in the budget is prudent.
- Septic: Confirm system age, permits, and capacity. On clay or shallow bedrock, tertiary treatment may be required. Replacement costs can reach five figures.
- Driveway and road access: Year-round maintained municipal road frontage is a plus for financing and resale. Access on a seasonal road may limit lender options and winter usability.
- Hydro and internet: Three-phase hydro is rare outside ag/commercial corridors. For broadband, check fibre expansion plans; Starlink is common in remote segments.

Environmental, forestry, and farm value on a 100 acre property
Timber and soils can materially influence value and taxes:
- Managed forest: Ontario's Managed Forest Tax Incentive Program can reduce property taxes if you implement an approved plan. A forester's cruise can estimate marketable timber and stewardship needs.
- Farmland class: Tile-drained Class 1–3 soils command premiums; rocky or wet sections reduce arable acreage. If the land is tenanted to a farmer, clarify crop agreements and possession dates.
- Species and wetlands: Protected species (e.g., butternut) or PSW mapping can limit clearing. Budget for environmental studies where flags exist.
KeyHomes.ca profiles varied terrain beyond Ottawa too; comparing Ontario's 100 acres with a house in Ontario to a Latchford 100-acre tract in the north can calibrate expectations about forest, rock, and lake country pricing.
Financing 100 acres with or without a home
Financing differs markedly between vacant land and a 100 acres with house for sale:
- Vacant land: Many banks want 35–50% down, shorter amortizations, and higher rates. Some cap acreage they will value (e.g., lending on the first 10–30 acres). Farm Credit Canada may be an option for agricultural operators.
- With a residence: If the dwelling is year-round and insurable, mainstream lenders may treat it like a residential mortgage (subject to appraisal). Outbuildings add value variably.
- Cash flow planning: Carrying costs can be benchmarked against in-town options; see KeyHomes.ca's overview of Ottawa all-inclusive house options when mapping monthly budgets, taxes, and utilities.
Work with a mortgage broker experienced in rural and ag files; appraisers may require a longer lead time and comparable sales can be sparse.
Taxes and closing costs to watch
- HST: Vacant land, new construction, or farm assets can trigger HST; used residential (house and immediately surrounding land) is generally HST-exempt. Mixed-use parcels can be complex—get an accountant's read.
- Ontario Land Transfer Tax: Payable on closing; Ottawa has no municipal LTT (unlike Toronto).
- NRST: Non‑Resident Speculation Tax may apply to purchases that include residential property (1–6 units), even on a 100 acre property with a house. Exemptions exist; verify current rules.
- Property tax class: Farmland and managed forest classes can reduce rates if eligibility criteria are met.
Short-term rentals and rural hospitality
Ottawa's Short-Term Rental By-law primarily limits STRs to a host's principal residence, with a defined “cottage rental area” where seasonal rentals may be permitted subject to registration and other conditions. A 100 acre property for sale with a cabin or second dwelling is not automatically STR-eligible. Confirm whether the parcel lies in a permitted area and whether the dwelling qualifies before underwriting STR income.
Seasonal market trends for large rural tracts
Inventory for 100 acre property types tends to swell in late spring and early summer when ground is visible and access is easy. Serious buyers do transact in winter—sometimes at a discount—but expect constraints: frozen wells can't be tested, buried infrastructure is harder to inspect, and forestry access roads may be impassable without plowing. Fall is often a balanced window for walkability (leaves down) and contractor availability for estimates.
Resale potential: what drives exit value on 100 acres
Resale hinges on a mix of practical and lifestyle features:
- Proximity: Commute times to Kanata tech parks, the 417, or village centres matter. Dunrobin and Carp typically command stronger demand than very remote tracts.
- Road and internet: Year-round access and fibre availability broaden the buyer pool.
- Water and topography: Creek frontage, rolling elevation, and mature hardwoods add appeal. Extensive EP or floodplain can reduce flexibility.
- Outbuildings: Legal, well-maintained barns/shops enhance value; unpermitted structures can drag it down.
Urban comparables are helpful for benchmarking broader Ottawa demand; see KeyHomes.ca's Dovercourt Ottawa urban comparables to contrast rural premiums/discounts relative to core neighbourhoods.
Due diligence checklist for a 100 acre property
- Title and survey: Order a current plan of survey or reference plan; confirm legal access, easements, and any Crown or aggregate rights.
- Planning/zoning: Obtain written confirmation of permitted uses, severance history, and any site-specific exceptions.
- Environmental: Check conservation authority mapping, PSW, and floodplain; commission studies if development is planned.
- Services: Test well potability/flow; inspect septic; confirm hydro capacity; price driveway and site works.
- Taxes and programs: Evaluate HST implications, farmland/managed forest eligibility, and any farm lease arrangements.
Examples and scenarios: Ottawa and beyond
Not all 100-acre opportunities look the same, even within Eastern Ontario. A farm-like tract such as the Warren Road farm offering can trade on soil quality and outbuildings, while a recreational parcel near water like Black Bay in Petawawa emphasizes lifestyle, trails, and hunting potential. Comparing cross-province markets helps set expectations, too: KeyHomes.ca's snapshots of the Muskoka 100-acre market, British Columbia 100-acre listings, and Nova Scotia 100-acre properties show how terrain, climate, and regulation shift value and carrying costs.
If your goal is a 100 acres with house for sale in Ontario within weekend range of the city, browsing consolidated options—such as KeyHomes.ca's page for 100 acres with a house in Ontario—can help refine features and budget bands before you commit to site visits.
Lifestyle appeal: why a 100 acre house resonates
Beyond investment arithmetic, a 100 acre property anchors a lifestyle: privacy, dark skies, trail systems, space for horses or a sugar bush. For some buyers, a 100 acre house enables multigenerational living with a second dwelling (where zoning allows). Others prioritize a cabin and abundant wildlife. Ottawa's rural mosaic lets you choose between farmland vistas, shield rock and pines, or mixed hardwood stands.
Buyer caveats and pro tips that save money
- Don't assume severability: Even a perfect 100 acre tract might have no additional lot potential under current policy.
- Budget soft costs: Survey, planning opinions, environmental screening, and driveway/culvert permits add up.
- Time your inspections: Spring thaw reveals drainage; late summer shows well performance; winter tests access.
- Insurance check: Confirm availability for wood stoves, solid-fuel boilers, and remote fire response.
