The past and future of psychology in Canada are addressed from the per
spective of different challenges to the unity of the discipline and pr
ofession. A number of current forces that affect the current status of
psychology, as well as an emerging set of forces, are discussed. It i
s argued that psychology is not a single phenomenon, but that there ar
e several psychologies. These psychologies, with their attendant push
towards multiple perspective and organizations, are seen as a sign of
the strong diversity of psychology. The author argues that diversity i
n psychology should be accepted and used for mutual gain, rather than
taken as a sign of the failure of psychology.
