Internationalism has long been central to Canadian foreign policy. Although
often invoked by governments and individuals, and much debated, it remains
an ill-defined, even obscure concept. This article assesses empirically ho
w the Canadian public regards internationalism, and explores the underlying
structure of internationalist attitudes. Public opinion data from 1985 pro
vide evidence of four dimensions of attitudes: active, economic, liberal -c
onservative and independent internationalism. There is a strong consensus o
n the first two types of internationalism but no such consensus behind the
others. Scattered data from across the post-Second World War period seem to
support these findings. Using such a typology of internationalism may both
illuminate debates on Canadian foreign policy and advance studies of Canad
ian public attitudes.
