 DND preferred the South Shore port town of Shelburne with its large natural harbour and deepwater port under development since fall 1941 at (and an adjacent seaplane patrol base opened in spring 1942 at RCAF Station Shelburne), however it is presumed that political pressure from J.L.Illsley, the federal Minister of Finance and MP for Digby—Annapolis—Kings forced DND to reconsider.A location in Ilsley's riding on the shallower but more protected Annapolis Basin straddling the western border of Clementsport and eastern border of Deep Brook was quickly adopted.
