Smith Falls is not a probable target of a nuclear attack but it has a three-fold role to play. Major General G.S Hatton, of Ottawa, deputy coordinator of Civil Defence for Canada, told members of the Smiths Falls Rotary Club Friday. The role of Smiths Falls, if a nuclear bomb were to chance to go off a few miles upwind of the town is very slight. But, we need to justify a policy of evacuation for the surrounding areas General Hatton declared.
The dangers from “fall-out” would be to-stand fast, and to act as a reception-centre for evacuees. Those evacuees from Ottawa and surrounding area would be sent to places like Smiths Falls to stay put and meet the danger of the “fall out” from the bomb”.
Lethal radio active “fall-out” from an H Bomb covers roughly 20 times the damage area of the bomb. In view of probability that the number of random bombs that would fall in Canada under the circumstances we visualize, would be greater than the number of bombs aimed at Canadian cities, we must all pay attention to this ‘fall out” menace the speaker said.
Smiths Falls must reserve roads and be the reception area and the population of Smiths Falls would need to stay put and offer help where ever needed. If people panic and leave in a disorganized manner greater numbers might be killed because of the clash of unorganization.
In the Phase “A” plan Smiths Falls should be prepared to take in 13,200 evacuees during a pre-attack of non essential personel from the targeted areas. In Plan B the planned withdrawl of the remaining population of those cities or towns on alert Smith Falls would handle 10,100. (Feb.1977)
Calculations demonstrate that one megaton of fission, typical of a two-megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 mi) across for five minutes. Total destruction spread over an area of about 3 square miles. Over a third of the 50,000 buildings in the target area of Nagasaki were destroyed or seriously damaged. Files from Ottawa Journal 1977
So would Smiths Falls be a logical “safe place” ? I had questions about that myself. When I went to the Diefunker years ago I saw the grim facts. Anyone who was in that bunker was safe, but if you were in the surrounding areas you were toast. A grim reminder who really comes first.
Diefenbunker Carp, Ontario
The safety of its nuclear roof would allow the Canadian government to operate safely underground for 30 days in order to assist with the governance and rebuilding of the country. A series of Emergency Government Headquarters bunkers were built across Canada and, as the largest, the federal government bunker would come to be known as the Central Emergency Government Headquarters (CEGHQ Carp).
When building began in 1959, it was a top-secret operation under the code name Project Emergency Army Signals Establishment (EASE). The former Montgomery farm in Carp was chosen as the perfect site for a 75 foot underground bunker: it was within evacuation distance of downtown Ottawa, it was in a natural valley, and it had the ideal geological conditions for protection.
