Are Building Permits Public Record in Ontario?

Published July 23, 2026

Are building permits public record in Ontario?

Short answer: Yes. A building permit issued by an Ontario municipality is public information, and Toronto publishes its active permits as an open dataset you can search by address for free.

A building permit is not a private document between the owner and the City. The record of what was permitted, where, and its current status is open to anyone who asks. Most Ontario municipalities will disclose that record on request. Toronto goes a step further and publishes its active building permits as open data, so you do not need to file a request or visit a counter to read them.

That open record is the entire basis for this site. PermitIndex indexes 27,839 Toronto building permits issued in the trailing twelve months as of Jul 16, 2026, drawn straight from the City's published data. You can search any Toronto address and see the permits on file in seconds, with no login. The rest of this guide covers what that record does and does not tell you, and how to read it.

What "public record" actually means here

Public record means the fact of the permit is disclosable. It does not mean every document in the file is published. It helps to separate the two.

What the public permit record shows:

• The property address the permit was issued against.
• The type of work, classified by trade and permit type.
• The permit status: whether it is under review, issued, or closed.
• The dates the City recorded for the application and issuance.

What it does not show:

• The owner, the applicant, or the contractor by name.
• The architectural drawings or engineering documents filed with the application.
• Inspection results, deficiency notes, or correspondence with the plans examiner.

So the record answers "what has been permitted at this address, and where does it stand," and it stays silent on who and how well. That boundary is deliberate. It is why a permit search sits alongside a home inspection rather than replacing one, and it is why you can research a property without exposing anyone's personal information.

Why the record is public in the first place

Two forces make permit information open. The first is the nature of a municipality: a City is a public body, and the permits it issues are records of a regulatory act, not private correspondence. The second is Ontario's access-to-information regime. Municipal records are governed by the Municipal Freedom of Information and Protection of Privacy Act, which starts from a presumption of openness for records that are not personal information. The City of Toronto's building and permits service is built around that presumption, which is why the active-permit dataset can be published for anyone to search.

The practical upshot: you do not need a reason, a relationship to the property, or a professional's help to look up a permit. The bar is that the information exists in the City's record and is not somebody's private data.

How to look up a permit by address

You have two routes, one official and one faster.

The official route is the City of Toronto's open-data record, which underlies everything here. It is authoritative and free, and it is the right citation when you need one. It is published through the City's Open Data portal, and the data sources page explains exactly which dataset that is and how often it refreshes.

The faster route is to search by address on PermitIndex. Type a street address and you get the permits the City holds for it, already classified by trade and dated, without reading a raw data file. If you are weighing how long a project might take once it is filed, the Toronto permit wait times page reports the median approval lag by trade from the same record.

How to read a permit's status

The status field is where most confusion happens, so it is worth reading plainly. A permit under review has been applied for but not yet issued: the City is still examining the plans. An issued permit means the work is authorized and may be underway. A closed or completed permit means the file is done, usually after a final inspection. A revoked or cancelled permit never proceeded.

The status tells you where the paperwork stands. It does not certify the quality of the work or that every inspection passed cleanly, because inspection detail is not part of the public dataset. A permit can be issued and the project never built, or closed on paper while a punch list lingers. Treat status as a project's paperwork state, not a warranty, and pair it with your own inspection when the stakes are a purchase. When a listing claims a renovation was "fully permitted," the status field is where you check that claim against the City's own record rather than the seller's word.

The one limit worth stating plainly

The City's open dataset covers active permits. Records leave it as projects close out and age off. That means an address with no permits on record is not proof that no work was ever permitted there, only that nothing is currently on the active register. For a recent renovation the record is reliable; for work done decades ago it may simply have aged out. Read an empty result as "nothing active," not "nothing ever."

If you do find work at a property that has no matching permit and clearly should have one, that is a question for a qualified inspector or the City's building division, not something the public record resolves on its own. The record is a strong first pass, not the final word.
