CNSC Releases Study of Mortality in Port Hope, 1956-1997
Nuclear Safety Commission
– The Canadian Nuclear Safety Commission (CNSC) today released the results
of a study entitled “Cancer and General Mortality in Port Hope, 1956 –
1997”. The study, carried out by Health Canada and subjected to a
scientific peer review by independent scientists, found that the overall
cancer mortality rates in the town of Port Hope, Ontario are comparable to
rates throughout the Province of Ontario.
The study was commissioned by the CNSC and conducted by scientists at Health
Using data from the Canadian Mortality Database (CMDB), the study compared
rates of cancer and other causes of death in Port Hope with provincial death
rates, comparing death rates back to as early as 1956. It also compared
cancer mortality results with a previous cancer incidence study conducted
for the Port Hope area, results of which were released in August 2000.
The findings of this recent study are consistent with the earlier cancer
incidence report. On the whole, the study findings demonstrate that the
patterns of cancer mortality and incidence in Port Hope are no different
from those throughout Ontario.
A consistently increased mortality from circulatory disease was observed.
This relative excess of mortality from circulatory diseases is not likely to
be due to environmental factors particular to Port Hope, in part because
elevated rates were also observed in the much larger Northumberland Census
Division which includes Port Hope.
