Provincial parks protect a representative sample of Ontario's earth science features. To help achieve this task, geological features have been defined as the physical elements of the natural landscape, created by geologic processes and distinguished by their age, stratigraphy (layering) and topography (shape). Representative, features have been organized into 44 geological themes, while more than 1200 typical rock types, fossil assemblages, landforms and related geologic processes have been identified for protection. Close to one half of all these features already have been captured in our park system.

Geological research in provincial parks is encouraged. Researchers must submit an Application to Conduct Research and receive approval.
