This study is not concerned with the probability that such an enemy attack will be made. II Definitions of Terms Used Ground Zero *« The point on the .ground directly under the point of burst in the air Aiming Point - The point on the ground directly under the point where the bomb is aimed to be burst in the air No Rescue ** No organized and trained rescue is carried out, which means effectively that only people who are not trapped or who can escape by their own efforts survive Seriously Injured Hospitalized persons who would not report to work for a considerable period of time Lightly Injured First Aid cases who would be able to contribute to their work a few days after the attack Nighttime « The time during which people are in their normal places of residence Daytime « The time dxiring whioh people are at their normal places of work III Sources of Basic Information (a) Population Information on the nighttime distribution of population is based on a redistribution of the 1951 census returns in greater detail to show -rae population of individual city blocks. This is considered for the purpose of this study a sufficiently good approximation to the nighttime distribution of population. It has not been possible at this time to estimate the daytime distribution of population. 000139 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET CANADIAN EYES ONLY - 2 (b) Vital Points Information on Vital Points was taken from the 1953 List of Vital Points, which is the work of the Interdepartmental Committee on Vital Points, The list for the Toronto area is given in Appendix "A", (° ) Scientific Data Basic data on the effects of atomic bomb explosions on people and structures was prepared by the Defence Research Board (Scientific Adviser to the Civil Defence Co-ordinator). Factors Considered in Selecting Aiming Points for Study The effects of an attack on a city vary widely with the location of the bomb burst. As it is not considered practicable to study all possible points of burst, a series of Aiming Points have been selected which are calculated to give the maximum effect on population and on different groupings of vital points. The effects of an attack vary widely with the energy released by the bomb. As it is not possible to estimate the energy level of the bombraostlikely to be used, separate estimates were made for a bomb with the lowest probable energy and the highest energy level. The effects on people also vary widely with circularstances of warning and rescue. A series of estimates were therefore made for different conditions of warning and rescue. The estimates made for conditions WITH RESCUE are for ideal rescue conditions with organized and trained rescue teams, in temperate climates and when the atomic attack is unsupported by other weapons. In spite of rescue efforts casualties would tend towards those given for NO RESCUE under severe winter conditions, or if Chemical Warfare attack were combined with atomic attack or if the spread of fire were extensive. Conditions of visibility would also alter the effeot of an attack, Poor visibility would reduce the extent of fire and the number of radiation casualties and would have some effect on the chances of pinpointing the target from the air. All calculations are based on an average clear day over a city with a visibility of about six miles. For the city of Toronto an Aiming Point was chosen to give the maximum effect on the nighttime distribution of population. This Aiming Point also gives the maximum effect on one grouping of Vital Points considered collectively. A total of eight Aiming points was chosen to give the maximum effect on other groupings of Vital Points. �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET CANADIAN EYES ONLY ** 3 ** V Results of the Study of the City of Toronto A nighttime attack on this city could result in casualties among 15-20$ of the population if a 20 Kiloton bomb were used, depending on conditions of warning and rescue; and 25-40$ if a 100 Kiloton bomb were used; and would cause varying degrees damage to several Vital points, A nighttime attack on the various groupings of Vital Points by a 20 Kiloton bomb would result in casualties among ^5-15$ of the population, depending on conditions of warning and rescue, and on the location of the Aiming Point being considered; and cause severe damage to the particular grouping of Vital Points. A nighttime attack by a 100 Kiloton bomb would cause casualties among ^15-30% of the population and cause more widespread destruction to Vital Points. (a) Effects on Population The effect of an attack on the nighttime population is given in Tables I and II for each Aiming Point and for different conditions of warning and rescue. (b) Effects on Vital Points A summary of the effeot on Vital Points is given in Table III for each Aiming Point. The extent of damage to Vital Points and the effect on their various functions is also described below for each of the Aiming Points, The relative importance of each Vital Point to the Canadian - U.S. war effort is indicated by the category (AA, A, B or C ) , which is given for each Vital Point in Appendix "A". A definition of each of the categories is also given in Appendix "A". 000141 �.- Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a l'informati\ -.

(d) Effects on Morale It is expected that the effect on morale in large centres of population in Canada, and at least the northern parts of the United States, would be much the same whichever city is attacked by an atomic bomb. The effect will probably be somewhat proportionate to the size of the casualties inflicted by individual bombs and by the number of cities attacked. VI Air Navigation Aspects of an Attack With the equipment at present available to the Russian Long Range Air Force, Toronto would be an exceptionally easy target to locate on either a high or low level attack under any weather conditions for a well trained navigator not familiar with the area. Accuracy in identifying specific Aiming Points is a more critical aspect. However the Vital Points are distributed over most of the city, and an atomic explosion over many parts of the built up area would cause serious damage to both Vital Points and population; though of a lesser magnitude than described by this report. 000167 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TABLE I - CASUALTY ESTIMATES - CITY OF TORONTO TOP SECRET NIGHTTIME ATTACK 20 K i l o t o n Bomb ' .

They have been adapted for the present study by raising those points which are important to the joint Canadian U.S. war effort from Category "A" to a superior Category "AA", and by restating the significance of the categories. The categories used are as follows: Category "AA" Individual plants or buildings of sufficient importance to the North American war effort to be considered possible atomic bomb targets, irrespective of any effects of an A-bomb attack on the target on other Vital Points, Additional effects will, however, play a part in determining the relative importance of Category "AA" targets and they have, therefore, been studied and reported. Category "A" Individual plants or buildings not of sufficient importance to the North American war effort to be considered A-bomb targets by themselves, but which may become A-bomb targets if the other effects of the explosion of a bomb over the target would produce a sufficient cumulative effect on population and other Vital Points, Category "B" Important points to be considered in conjunction with attacks on Category "AA" and Category "A" targets. Category "0" Minor points bo be considered in conjunction with attacks on Category "AA" and Category "A" targets. 000195 � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
