The former Diocesan College is now know as University Hall Residence, and in conjunction Presbyterian College ('Pres Res'), offers co-ed, dormitory-style accommodations to 75 first-year McGill students.
Built in 1962, Gardner Hall is one of three residence halls located in MacDonald Park, a parcel of land on Mount Royal donated to McGill by Sir William Macdonald. These halls are commonly called the upper residences.
The EcoResidence is McGill's most innovative student accommodation. From the shell of an old residence, EcoRes was created almost entirely out of recycled materials, and features state of the art heating and ventilation systems to maximize energy conservation.
