The Geological Survey of Canada (GSC), a Branch of Natural Resources Canada (NRCan) has a mandate to advance understanding of the geological resources of Canada. The GSC has recently published the first complete three-dimensional geological model for southern Ontario (Carter et al. 2019). The GSC is planning to update this model over the next 3 years and convert the 54 layer model to a simplified hydro stratigraphic model to support regional-scale groundwater modelling. To improve the model requires extensive Quality Assurance (QA) and Quality Control (QC) of the petroleum database entries and analysis of physical property data. All of the data is held by the Ontario Ministry of Natural Resources and Forestry Petroleum Operations Section in London, Ontario. The only point of access to this data is via the Ontario Oil, Gas and Salt Resources Library (OGSRL). The Ontario Oil Gas and Salt Resources Corporation (Corporation) is the “Original Trustee” to a Trust Agreement signed with the Government of Ontario in 1998 to manage and operate the Ontario Oil, Gas and Salt Resources Library.
