The first digital version of the Canadian Ecological Framework was developed in a joint initiative between Environment Canada (EC) and Agriculture and Agri-Food Canada (AAFC) between 1992 and 1995 and published in 1996. In collaboration with the CCEA, EC performed the consultative and policy planning while AAFC completed the GIS analysis and spatial interpretations. The spatial analysis utilized physiographic and climatic data interpreted to the Soil Landscapes of Canada (SLC), a national 1:1,000,00 soil map and data product.
