Severance & Legal Lots in Ontario: Is This Parcel Actually Buildable?

You confirm it through a title and planning review – normally your real estate lawyer’s job – not by trusting the listing. They check that the parcel is a legal lot of record that can be conveyed and built on, that it wasn’t created improperly, that it hasn’t merged with an adjacent lot under common ownership, and that it has legal road access. The municipality’s planning department can confirm whether a lot is recognized and whether a severance was ever completed. Make confirming legal-lot status a written condition of your offer, because if the parcel isn’t a legal building lot, you cannot get a building permit on it.

A severance, officially a consent, is the planning approval to divide one parcel of land into two or more separate lots. It’s governed by the Planning Act and decided locally by the Committee of Adjustment or a land division committee. The process runs from a pre-application consultation, to a formal application with a survey, to public notice, to a decision that usually comes with conditions, and finally to a certificate once those conditions are met. Only when the certificate is issued does the new lot legally exist – until then it’s a proposal, not a parcel you can build on or get clean financing for.

A decision typically takes about two to three months from a complete application, and then satisfying the conditions and getting the certificate issued adds more time on top. Costs vary widely by municipality, but a straightforward Ontario severance commonly runs in the range of $5,000 to $15,000 or more once you include the municipal application fees, a survey or reference plan (often around $3,000), legal fees, and any condition costs such as fees or studies. Big cities run higher. Confirm the current fees with your local planning department, since they change and differ across municipalities.

Make your purchase conditional on the severance being completed, not merely applied for – meaning the consent is granted, all conditions are satisfied, and the certificate is issued. A pending severance can be refused, conditioned in ways that cost money, or appealed, and the consent lapses if it isn’t acted on in time (generally two years). You also want to confirm the new lot will have legal road access and meet zoning for the home you intend to build. Your lawyer should review the consent and its conditions before you waive conditions, so you’re not buying a parcel that doesn’t legally exist yet.

Merger of title happens when two abutting parcels come into the same ownership and, under the Planning Act, are treated in law as a single lot. It often surprises people who buy two adjacent lots expecting to build on one and sell or build on the other, only to learn the law now sees one parcel – and re-separating them requires a fresh severance. It can also happen accidentally over the years through how properties were bought and held. Before you rely on having two separate buildable lots, have your lawyer confirm they haven’t merged, because the assumption that “two deeds means two lots” is not always true.

A lot can be landlocked, and it’s a serious problem. A new lot generally can’t be created without proper legal road access, and a severance can be refused on access grounds. If a parcel only abuts an unopened road allowance, or relies on crossing a neighbour’s land without a registered right-of-way, you may not be able to get an entrance approved or a building permit issued, and financing gets difficult too. If access depends on a right-of-way, your lawyer needs to confirm it’s properly registered and adequate. Reading the survey carefully is the first place these access problems show up.

The approval path is different in unorganized territory – a regional planning board may handle consents rather than a municipal Committee of Adjustment, and local zoning may be limited or absent. But you still generally need a properly created legal lot to convey and finance the property, so the legal-lot question does not disappear. And importantly, even in areas where a building permit isn’t required, Building Code standards still apply to the home you construct. Treat “no permit needed” as a process difference, not a green light to skip due diligence on lot status, access, and how the home must be built.
