Perth and Walsh County
Perth is associated with Walsh County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Perth by land and water
The Census records 1.24 square miles of water within Perth, or 3.5% of its total area. It is 2.5 percentage points higher than the 1% recorded for Walsh County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Perth township has 99.9% of the land area of nearby Sarnia township (34.8 square miles). These areas describe boundaries, not comparable property prices.
