The cost sharing was for $305 million (USAF) and $135 million (RCAF) that included "tying into...32 ground-to-air radio sites." The schedule for CADIN gap-filler radar stations included those for "P-20F, London, Ontario; C-4-C, Brampton. Ontario; C-5-C, Mt Carleton, New Brunswick; and C-6-D, Les Etroits.
