This building, on the campus of McGill University in Montreal, was built to accommodate the university's physics department and in particular its Radiation Laboratory and Cyclotron.  In 1964 it was named after the McGill physicist John Stuart Foster. 



The Montreal Gazette published a news story about the naming of the building on September 14 of that year, saying that, "... Professor J. S. Foster, known throughout the scientific world for his original contributions and discoveries in nuclear physics, retired as director of the laboratory in 1960 and is now living in Berkeley, Calif."

The university says of the building that it was, when it was built, "... a purely functional concrete structure that provided necessary space and more modern equipment for experiments in Physics."

Today, the Foster Laboratory building has been incorporated into the M. H. Wong building, home to the Chemical Engineering laboratories.  The university says that, "The Foster Wing, which will be used as offices, has had classrooms and labs added to both its west side and the top of the building, designated for Metallurgical Engineering labs."
