Although Canada has the second largest land area of any nation, only ten percent of that area is, in practical terms, suitable for agriculture. From this ten percent, the nation obtains a great variety of produce, including large quantities of food for the world market. Owing to the dependence of Canada on the produce of the land, it is essential to understand the limits of the land resource, the location of prime lands, and the forces that may affect the capability of the land resource to continue to serve Canada's needs. After a decade of data collection and analysis, the Canada Land Inventory (CLI) is nearing completion. This publication details the preliminary results for the agriculture sector, as processed by the Canada Geographic Information System (CGIS) from CLI data.
