The U.S. removed the last of its nuclear bomb components from Canada in June, [1984], but had originally deployed bombs on Canadian soil as far back as 1950.

The report doesn't list sites or numbers. But it does cite a 40-year-old accident in Canada as proof of the danger unwittingly faced by citizens unaware that their countries were hosting U.S. weapons.

``Very few members of the Canadian government knew of this arrangement (in the 1950s),'' the authors state. After prime minister Louis St. Laurent approved a six-week deployment in July and August, 1950, a U.S. bomber had engine trouble while ferrying bomb assemblies from an Arizona air force base to Goose Bay, Labrador.

The U.S. ``lost'' a bomb assembly in the St. Lawrence River in 1950 and didn't acknowledge the accident until Pentagon documents were declassified in 1990, the scientists write.

The Star reported in January, 1997 - based on a study of nuclear weapons in Canada by military historian John Clearwater - that the bomb, without its nuclear components aboard, was detonated at 760 metres over the St. Lawrence near Rivière-du-Loup on Nov. 10, 1950.
