AbstractOver 95% of Canada’s known coal resources are found in the sedimentary basins of the Interior Platform and eastern Cordillera (Fig. 6B.1); a minor amount is found in the Moose River Basin of the Hudson Platform. This distribution is shown in Table 6B.1, which summarizes coal resources for all of Canada.
