About the Coal Industry - Coal Association

Coal is by far Canada’s most abundant fossil fuel, with 6.6 billion tonnes of recoverable coal reserves. Canada has anthracite, bituminous, sub-bituminous, and lignite coal deposits. More than 90% of Canada’s coal deposits are located in western provinces, which provides a strategic advantage because of the close proximity of west coast ports.

What are the types of coal?

Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers. Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon.
