The Ontario Geological Survey (OGS) is an administrative Branch of the Ontario Ministry of Northern Development, Mines and Forestry. It is responsible for documenting and communicating the geology of Ontario, and manages the Assessment File Research Imaging database.
OGS helps people understand how to apply the geological knowledge about Ontario to address a range of public policy issues. The OGS is a public good organization. Its geological survey function is mandated by the Ontario Government. OGS has no regulatory responsibility. Ontario's geology includes: a) the rock (bedrock); b) the deposits of sand, gravel, and till left by the glaciers; c) the mineral resources and potential; d) the energy resource potential within the rocks and soils; and e) the groundwater aquifers that contain groundwater resources. An understanding of what is at, and below, our feet is fundamental to human existence on the Earth, to understand the environment and habitats, and our ability to adapt to future changes, such as global warming. This geological knowledge is used to assess Earth resource potential, to attract investment, to ensure the health and safety of Ontario people from geo-hazards, and to plan the present and future use of the land. The OGS also collaborates with Ontario's Aboriginal people to achieve a mutual understanding, mutual respect, and to achieve mutual interests. The OGS is a science-based organization that conducts field studies.
