The mall was given a face lift in 1980 and renamed LONDON EATON SQUARE. 6 years later, Canadian real estate developer and financier Robert Campeau acquired the property. A major renovation and expansion was done, with the shiny new GALLERIA LONDON debuting in August 1989. Above is a circa-1998 plan of the complex.
