The Freshwater Fishes of Canada by Scott and Crossman is considered to be the definitive book on the Canadian freshwater fish fauna.  The composition and distribution of the fish fauna has changed considerably since the publication of Freshwater Fishes of Canada in 1973. There are 26 species, not included in 1973 now established in Canada as a result of new introductions, changing taxonomy, and additional field surveys. The additional field surveys and more recently published regional books have improved our knowledge of the distributions of all freshwater fishes in Canada. Revising the Freshwater Fishes of Canada in its entirety is a daunting task. Rather than revise it in a single volume a supplement, Freshwater Fishes of Canada New to the Fauna Since 1973, will include full species accounts in the same format as the original book for the 26 species established since 1973. A second supplement, An Atlas of the Freshwater Fishes of Canada Annotated with an Identification Key, will include update distribution maps and identification key for all freshwater fishes in Canada. There are insufficient data to produce dot distributions maps; therefore, shaded distribution maps based on tertiary watersheds (n=966) will be compiled based on known records and the expert opinion of regional experts.
