In 1939 Smith joined the federal Department of Transport (DOT) and began work to help develop Canada's wartime signal monitoring system.

Smith claimed his research showed that gravity could be created and controlled and he had been working on an anti-gravity device before he died of cancer in 1962, but had taken it apart, telling his wife that the world was not ready for it.
In 2015 the world's first detection of gravitational waves took place at the Laser Interferometer Gravitational-Wave Observatories (LIGO) located at Hanford, Washington and Livingston, Louisiana.
