THE CANADIAN AMBASSADOR, WASHINGTON, D. C.
Your letter No. 19 of January 3 and other corresp ond enc e

Subject:

United States Strategic Air Command Projects

The United States proposal for a "canopy"
agreement concerning the use of facilities in Canada
by the Strategic Air Command was discussed at a meeting
with Mr. Pearson, Mr. Claxton, Mr. Robertson, General
Foulkes, A/V/M James and myself. The subject has also
been discussed with the Minister several times and the
Prime Minister. The comments which follow are based on
these discussions, but they should be regarded as my
own, since it is felt that the matter should be kept on
this more or less informal basis for the present.

As you have suggested, we should consider

the United States request for a "canopy" agreement in
the broader setting of the talks between.President Truman
and Mr. Attlee about the use of atomic weapons. I quite
agree with your view that there is a very real risk of
misunderstanding arising between the United States and
the United Kingdom as to the nature of the commitment
which was given by President Truman. The United Kingdom
Government apparently feels that a specific commitment
for consultation in advance of use of the bomb has been
made by the President. On the other hand, Mr. Acheson
was quite specific in his secret statement to the Senate
Foreign Relations Committee that there was no commitment
to any government regarding prior consent. A close
examination of the press communique issued after these
talks and the memorandum of the conversation between Mr.
Ignatieff and Mr. Arneson on December 11, 1950, would
seem clearly to support Mr. Acheson’s statement. The
concluding sentence of the memorandum of the conversation
with Mr. Arneson, if a correct statement of the United
States Government's views, clearly indicates that the
United States Government has committed itself only to
consultation "on the developing int’ernational situation
and the military measures which it called for, rather
than upon the use, in a particular situation, of atomic
or any other kind of weapons". Canada is assured of only
equal treatment in this respect.
3.
The draft canopy agreement forwarded with
your letter No. 19 of January 3, if accepted by us in its
present form, would constitute, in effect, advance consent
to the use, subject to notification, of facilities in
Canada by Strategic Air Command in preparing for carrying
i out operations in atomic warfare. Although the phrase
2 . .

,/)

"consultation and notification procedure", is used
in the final paragraph, it is fairly clear from
the text as a whole that the "consultation" envisaged
would not necessarily entitle the Canadian Government
to refuse. In short, the canopy agreement as outlined
would seem to leave the Canadian Government with
little, if any, more control over the use for operational purposes by Strategic Air Command of facilities
in Canada than it has over policy under the TrumanAttlee formula.

4.

The desire of the United States authorities
in view of responsibilities under NATO for strategic air
operations, to have a free hand, subject to notification,
for the Strategic Air Command to overfly Canada and to
use Goose Bay and Harmon Field for operational purposes
is fully appreciated. At the same time, if the Canadian
Government agree to such an arrangement, it might well
forego any opportunity it may have of influencing policy
in the use of atomic weapons by reason of Canada’s
geographical location. In the event of an all-out war,
it would perhaps be unrealistic for the Canadian
Government to hope that it could really exercise an
effective influence on such policy. But it would clearly
seem unwise for it to "throw in its hand " in advance.

/

Such an argument, of course, can scarcely
5.
be put to the United States authorities. It might,
however, be pointed out to them that although the United
States has a responsibility under North Atlantic Treaty
arrangements for strategic air operations, and although
the Canadian Government would not wish in any way to
hinder the United States in the fulfillment of these
responsibilities, it is felt that it would be improper
for Canada as a sovereign nation to permit unrestricted
use in peacetime of facilities in Canadian territory for
these operations, even on assurance of notification in
advance of use.

6.

The above observations apply particularly

to the storage of fissionable components on Canadian
territory, to the overflight of Canadian territory by
planes carrying fissionable components, and to strikes
from bases in Canada. These are matters on which it
is felt the Canadian Government should be’consulted in
each case at the highest political level. The channel
for such matters should be civil rather than military.
The normal procedure would be for the State Department
to make its request to you, and for this request, on
receipt here, to be relayed at once to the Minister or
the Prime Minister. (I shall write you separately
suggesting a procedure for assuring security and speed).

Emergency situations may be envisaged
7.
when the utmost speed in dealing with a request would
be required, but I do not think the procedure suggested
would mean any more delay than if the request were forwarded through military channels. I cannot quite foresee
the Government being prepared to authorize the military
authorities here to decide on such a request. There

3 . .

" 3 should be no more delay in getting a decision from the
Ministers if a request were to come through diplomatic
channels than if it were to come through military channels.

8.

Arrangements could, I think, be made for
handling other than the above matters on a Service-toService basis. I have in mind such matters as training
programmes, the provision of storage facilities, the
deployment of aircraft, and even such matters as movement
and storage of bombs without fissionable components.
Having. agreed to facilities in. Canada for the Strategic
Air Command and having agreed to the division of responsibility under NATO, which leaves responsibility for
strategic air operations to the United States, I do not
see any objection to purely Service questions such as
the above being settled directly between the RCAF and
the USAF at whatever level they agree-. upon.

In conclusion, should the United States
9.
wish to proceed with negotiations for a canopy agreement,
I suggest the agreement should be placed squarely upon
agreed arrangements under the North Atlantic Treaty. A
reference might be written into the introductory part
of the United States Note to our common obligations
under the Treaty, to the special responsibility of the
United States for strategic air operations,and to the
agreement of Treaty nations through the Council Deputies
that member nations should agree to give immediate and
special attention to the granting to the United States
of appropriate facilities for fulfillment of its responsibilities (Document D-D/183). I am not suggesting that
the text of the Note need refer to this Document or quote
its language, but that it should reflect agreed North
Atlantic policies under which both the Canadian and United
States Government would be acting.
I suggest that you present these views
orally to the State Department. We have tried our hands
at a redraft of their proposed Note enclosed in your
letter NS. 19 of January 3, but with unsatisfactory
results. In any case it is perhaps preferable to let
them do their own redrafting in the light of our comments,
should they wish to proceed with the proposed note.
