OS2 zone polygons (By-law 2010-0050)The outline is the Town of Halton Hills boundary.

Where OS2 applies

Polygons and hectares by the Town of Halton Hills’ outlines, each polygon placed by a point inside it. 52 zone polygons fall outside every outline.

Wards: Ward 3 (18), Ward 1 (14), Ward 4 (14), Ward 2 (6).


Exceptions, holding and other markers

The markers the layer records on OS2 polygons. Their terms are written only in the by-law; each line says where.

Site-specific exception (1 polygons)
114-FSection 2.5: a number in brackets after a zone symbol refers to a site-specific exception listed in Part 13.
Drawn over another polygon
1 zone polygon sit inside another polygon on the layer (the map draws one zone over another without cutting a hole). Their hectares are counted here and in the other zone; the by-law map decides which applies.

What the zone permits

The permitted uses and regulations for OS2 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.
