What the record is
Mapped parcel lines are drawn for the City's own records and are not a survey: the legal boundaries are in the registered survey and the parcel register. The mapping is close enough to say whether a lot is 10 m or 15 m wide, not where a fence should stand.
The report line gives the mapped area in square metres and square feet with the approximate frontage and depth. Elsewhere, the parcel register on ONLand and the MPAC notice carry the lot's recorded dimensions.
