The first MGH was built at the corner of Craig Street (today St. Antoine) and St. Lawrence Boulevard and only had 24 beds. Having outgrown this space, it moved to a new 72-bed building on Dorchester Boulevard (now René-Lévesque) at St. Dominique Street; today this facility is a long-term care centre. In 1924, the hospital merged with the Western General Hospital (currently the D & E wings of the former Montreal Children's Hospital) building at the corner of Tupper Street and Atwater Avenue. It moved to its current location in 1955.
