Description
The Physiography of southern Ontario, published by the Ontario Geological Survey, provides an overview of the glacial geology of southern Ontario.
The digital files were provided by the Ontario Ministry of Agriculture and Food in 2007 and comprise a generalized overview layer and more detailed data for several counties in Ontario. Other counties will be added as they become available.

Chapman, L. J.(Lyman John) and Donald F. Putnam. The Physiography of Southern Ontario [Ontario Geological Survey Special Volume 2), Third Edition. Government of Ontario, 1984.
The library has all editions. Search Primo for the copies.
