This archival study investigates the nature and development of Canadia
n attitudes and policy towards Antarctica between 1945 and 1962. Throu
ghout this period, the key continuity was the tendency to view Antarct
ic affairs from an arctic perspective. Canada, though becoming more pr
eoccupied with the Arctic and avoiding active involvement in Antarctic
a, found it difficult to ignore the more remote and distant southern p
olar region. Although the Arctic and Antarctic are distinct regions in
geographical, political, legal and other terms, they are both polar r
egions subject to a range of seemingly analogous controversies. As a r
esult, certain post-1945 developments affecting Antarctica were deemed
of potential relevance to its northern counterpart, thereby encouragi
ng the Canadian government to consider the nature of its political, le
gal, scientific and other interests in Antarctica. Canada's efforts to
remain on the sidelines were qualified by the fact that Antarctica wa
s treated as a significant policy interest by other states-most notabl
y, Australia, Britain and the United States-which not only kept the Ca
nadian government well informed about developments but also asked freq
uently for its views. In 1959 the conclusion of the Antarctic Treaty f
orced the Canadian government to consider whether or not to accede to
the treaty. In the event, the government, guided by a series of interd
epartmental exchanges, decided against accession, which did not take p
lace until 1988.
