Not every farm sale in Ontario transfers as a single, intact parcel with one house on it. Sometimes the farmhouse is severed off and sold separately from the working farmland, or a seller keeps the house for themselves while selling the land. If you are buying either half of a split farm property, understanding how that severance was — or needs to be — approved matters as much as the price.
Buying a farm with a residence in Ontario where a severance is involved means your due diligence has to cover the Planning Act consent process, not just the usual title and survey review.
What a "Retained Farmhouse" Severance Is
A retained-farmhouse (or "surplus farm dwelling") severance separates a farmhouse and a small surrounding lot from the larger farm parcel it sits on, creating two separately owned properties out of one. This commonly happens when a farm family sells the working land to a neighbouring or expanding operation but wants to keep the house, or when a buyer only wants the house and not the farming operation that comes with the rest of the acreage.
Severing land in Ontario is not something a seller can simply do by drawing a new line on a survey. Under the Planning Act (s. 50), conveying, mortgaging, or leasing part of a landholding generally requires municipal consent — this is the same "part-lot control" framework that catches a lot of ordinary property splits, and it applies to farm severances too.
Why Sellers Split the House From the Land
Reasons vary, but common ones include: the seller wants to retire in place while selling off the farming operation, an estate is being divided among heirs who want different things, or a buyer specifically wants the farmland for agricultural use without taking on an occupied residence. Municipalities that permit these severances often attach conditions meant to preserve the remaining farmland for agricultural use — for example, limiting the size of the severed house lot, or restricting whether another dwelling can later be built on the remaining farm parcel.
The Consent Process, in Plain Terms
- An application for consent is made to the local land-use planning authority (typically a committee of adjustment or land division committee), identifying the proposed new lot lines.
- Conditions are attached, if the consent is granted — commonly addressing lot size, access, servicing (well and septic), and restrictions meant to protect the remaining farmland from further development.
- The conditions must be fulfilled before the severance is finalized and the new deed can be registered.
- The severance is registered on title, creating two legally distinct parcels where there was previously one.
If any step was skipped — most commonly, if a "severance" was done informally without going through this process — the resulting arrangement may not be legally valid, which is a serious problem for a buyer relying on it.
Buying the House-Only Lot vs. the Farm-Only Parcel
| Buying the Severed House Lot | Buying the Remaining Farm Parcel | |
|---|---|---|
| What you're getting | The residence and a limited surrounding lot | Working farmland, typically without a residence |
| Common restrictions to check | Covenants limiting further development or lot size | Restrictions on building an additional dwelling |
| Shared infrastructure risk | Shared driveway, well, or septic arrangements with the farm parcel | Same, in reverse |
| Zoning fit | May need to confirm the house lot's zoning still supports residential use at its new, smaller size | May need to confirm remaining acreage still meets any minimum lot size for its zoning |
| Key document to request | Confirmation the severance consent was granted and its conditions satisfied | Same |
Red Flags to Check Before You Rely on a Severance
- The severance was done informally, without a documented municipal consent
- The conditions attached to the consent (servicing, access, restrictive covenants) were never registered or never fulfilled
- The severed house lot and remaining farm parcel share a well, septic system, or driveway without a formal, registered agreement governing that arrangement
- A restrictive covenant limits future building on the parcel you're buying, in a way that doesn't match your plans
Before You Waive Conditions
- [ ] Confirm the severance was approved through the proper municipal consent process, not done informally
- [ ] Get copies of the consent, its conditions, and proof the conditions were satisfied
- [ ] Check whether the house lot and farm parcel share any services (well, septic, driveway) and whether a registered agreement governs that sharing
- [ ] Review title for restrictive covenants tied to the severance, and confirm they don't conflict with your intended use
- [ ] Confirm the current zoning for the specific parcel you're buying supports your intended use, given its post-severance size
Frequently asked questions
What happens if the farmhouse was "severed" without going through the municipal consent process?
An informal severance done without proper municipal consent can mean the resulting property boundaries or ownership arrangement are not legally valid — a serious title problem. Have a lawyer review exactly how and when any severance occurred before you rely on it.
Can I build a second home on the farmland if the house was already severed off?
Often not without further consent, and many severance conditions specifically restrict additional dwellings on the remaining farm parcel to preserve it for agricultural use. Check the specific conditions attached to the original severance before assuming you can build.
Do I need a survey before buying a severed farm property?
A current survey is strongly advisable for any severed parcel, since boundary lines, shared access, and setback compliance are exactly the kind of details a severance can complicate. Your lawyer can advise on what survey work makes sense for your specific purchase.
Does buying farmland always require a lawyer familiar with severances?
Not every farm purchase involves a severance, but where one is involved — recently completed, in progress, or something you are hoping to pursue after closing — the Planning Act consent process adds a layer most residential purchases don't have, and it is worth having a lawyer experienced with it review your file.
