OS4 · Open Space Four

Where OS4 applies

Polygons and hectares by the Town of Halton Hills’ outlines, each polygon placed by a point inside it. 28 zone polygons fall outside every outline.

Wards: Ward 2 (13), Ward 1 (9), Ward 3 (6).

Exceptions, holding and other markers

The markers the layer records on OS4 polygons. Their terms are written only in the by-law; each line says where.

Site-specific exception (3 polygons)

34 (×2), 11Section 2.5: a number in brackets after a zone symbol refers to a site-specific exception listed in Part 13.

What the zone permits

The permitted uses and regulations for OS4 are set out in Part 10 of Comprehensive Zoning By-law 2010-0050 (PDF, Town of Halton Hills). HaltonHillsIQ does not paraphrase them: an exception, a holding provision or a later amendment can change what applies to one lot. The Town of Halton Hills’ Compliance Memo Request is the Town of Halton Hills’ own answer for a property. The interactive zoning map shows the zone on a single lot.
