* IMPORTANT MESSAGE * THIS WMS SERVICE WILL CLOSE ON SEPTEMBER 15, 2020. The surficial geology map collection consists of individually published surficial geology maps across Canada that have been released in the Canadian Geoscience Map Series format. Each map was created with a specific extent or scale which may result in data superimposition. These maps share a common science language (common legend) based on the Geological Survey of Canada’s Surficial Data Model. The map collection provides an effective easily accessible national surficial geological framework and context in a standardized format to all users.
