In September 1945, McGill University established a satellite campus called Sir William Dawson College at the Royal Canadian Air Force base in St. Johns (now Saint-Jean-sur-Richelieu), Quebec. This first incarnation of the college was set up to handle the overflow registration of servicemen after the Second World War. Populated mainly by engineering and science students who were required to live onsite, the college operated for five years. It was named after Sir William Dawson, a principal of McGill University from 1855 to 1893.
