What each status means for an owner or buyer

Designated (Part IV) 83
Designated individually under Part IV of the Ontario Heritage Act by a Town by-law. Altering the heritage attributes, or demolishing, needs the Town's consent.
Listed, not designated 894
On the register but not designated. Listing does not require a heritage permit for alterations, but an owner must give the Town 60 days' notice of an intention to demolish or remove a building or structure (Ontario Heritage Act, s. 27(9)).

Whether a specific address is on the register, and what work needs a heritage permit, is a question for the Town’s heritage planning staff; the register is the Town’s, and this copy is rebuilt from it rather than maintained separately.

Every property on the register 977

By status, then street. A linked address has its own page: every designated property, and every listed one the Town wrote a description for; the street numbers of the rest are listed by street.

How this database works

The Town of Milton publishes its heritage register as an open-data layer: one row per property, with its status under the Ontario Heritage Act, the designating by-law and, for some properties, a short description. MiltonIQ reproduces those values and texts verbatim and credited, and gives a page to every designated property and every listed property with a description.

The Town's Municipal Heritage Register (updated July 2026) states that the Register includes properties designated under Section 29 in Part IV of the Ontario Heritage Act, and properties listed under Section 27(3) that have not been designated. Source.

Checked against the Town’s own register document on October 8, 2026: Both carry 83 designated properties. After spelling is normalised, 35 PDF rows have no layer row and 25 layer rows have no PDF row; most are numbering differences on the same street (e.g. 255 Ruhl Drive in the PDF, 155 Ruhl Drive in the layer). The layer is published as the Town records it; the PDF is the Town's register document. The register document.

Nothing here is an opinion about a building’s merit. Dates are the Town’s, and several are ranges or circa dates; where the register records none, none is shown.
