Geography
Esquesing Township, of which the greatest part went to form Halton Hills, was favourably described in 1846:
The town is bisected by the
Niagara Escarpment

from southwest to northeast, and a significant portion of the rural area is located within the
provincial Greenbelt. Above the Escarpment, a large proportion of the rural area is classified as environmentally sensitive wetlands, and there are several sites that are licensed for aggregate extraction, for which expansion requires detailed environmental assessment. Below the Escarpment, the rural area is mainly agricultural, with the exception of an industrial area currently being developed between

Vegetation
Halton Hills is located in the transition zone between the Huron-Ontario Forest Section of the Great Lakes-St. Lawrence forest zone to the north and the Niagara Section of the
Carolinian forest

zone to the south. Both forest zones are part of the
Mixedwood Plains Ecozone. The natural vegetation in the Huron-Ontario Section is dominated by mixed wood forests. It is a transitional type between the southern deciduous forests and the northern coniferous forests. The forest communities of the Niagara Section are dominated by broad-leaved trees. Overall, Halton Hills consists predominantly of agricultural lands with scattered woodlands and wetlands. The woodlands are mainly deciduous forest and the wetlands are either
cedar swamp or
cattail marsh.

The trout have not returned, and anglers report that most of the fish have almost entirely disappeared from the area.
Geology
The physiography and distribution of surface material in the Town of Halton Hills are the result of glacial activity which took place in the
Late Wisconsinan Substage of the
Pleistocene Epoch
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was fin ...
. This period of time, which lasted from approximately 23,000 to 10,000 years ago, was marked by the repeated advance and melting back of massive, continental ice sheets.
The Niagara Escarpment dominates the physiography of the town and greatly influenced the pattern of glaciation in the region. The Escarpment, formed by erosion over millions of years, is a high relief bedrock scarp which trends to the north through the central part of the town. To the west, on the upper surface of the Escarpment, hummocky
morainic ridges deposited by glacial ice form part of the Horseshoe Moraines physiographic region. To the southeast below the Escarpment, is a smooth glacial till plain partially bevelled by
lacustrine action, which forms part of the South Slope and Peel Plain physiographic regions.

History

Both Georgetown and Acton, as well as the smaller communities in the rural area, have histories which go back about 200 years. Settlement began in the 1820s.
The hamlet of Hornby was home to the large Brain Brewery, established in 1845; it was eventually making 5,000 barrels of beer per year with ten employees. The facility closed when Prohibition started in 1916 and did not later reopen.
Halton Hills was formed in 1974 through the amalgamation of the former Towns of
Georgetown and
Acton, together with much of the former
Esquesing Township, and a small portion of the Town of
Oakville lying north of
