Between 1957 and 1963, Canada acquired numerous nuclear delivery systems to fulfill commitments to the defence of North America and the North Atlantic Treaty Organisation (NATO). In 1972, Pierre Trudeau’s government divested most of these systems. Much of the literature ascribes Trudeau’s decision to purely political reasons. By examining the contributions of two operational researchers from the Defence Research Board, Dr. R.J. Sutherland and Dr. George Lindsey, this article assesses the influence of professional advice on denuclearisation. This research has found that Lindsey and Sutherland provided a strategic grammar which helped shape the nature and timing of partial denuclearisation.
