In Northwest Territories, Ceratodon heterophyllus is found only on Prince Patrick Island.

Ceratodon heterophyllus has also been treated as C. purpureus forma heterophyllus (Kindberg) Britton, and R. R. Ireland (1980) considered it to be a variety of C. purpureus, but J. S. Burley and N. M. Pritchard (1990) provided ample evidence that it is a distinct species. The broadly ovate leaves of C. heterophyllus grade into some alpine variations of C. purpureus.
