Ottawa has always struggled with the concept of nuclear weapons based on Canadian soil. They never told the Canadian public the whole truth.
Canadian politicians down-played the notion of nuclear-armed BOMARCs based at North Bay, Ontario.
I caught glimpses and heard rumours during my CAF service during the 1970s and 1980s.
Canadian peace-niks protested on the Halifax Court House lawn, many miles away from where visiting submarines docked.
Rumor had it that nuclear depth-charges were held at the Bedford Basin bomb-dump in Nova Scotia.
While jogging around CFB Comox, B.C. I saw USAF Air Police behind a chain-link fence, so I guessed that they were guarding nuclear-tipped genie missiles for CF-101 Voodoo interceptors.
I was posted to CFB Baden-Sollingen, West Germany just as the last few. f-104 Stardighters retired, so nuclear bombs were gone, but I heard rumours.
