As the Town of Milton’s register records it, reproduced verbatim.

What the status means

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.

Whether a specific alteration needs a heritage permit is the Town’s call; ask its heritage planning staff before starting work. The designating by-law (16-1982 & 17-1982) sets out what is protected; the Town can provide it.
