Coal is by far Canada's most abundant fossil fuel, with billion tonnes of recoverable coal reserves. Canada has anthracite, bituminous, subbituminous, 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.
Lignite Uses. About 79 percent of lignite coal is used to generate electricity, percent is used to generate synthetic natural gas, and percent is used to produce fertilizer products (anhydrous ammonia ammonium sulfate). A very small percentage is used as home heating fuel, for use as fertilizer and for use as oil well drilling mud.
