UHN History

The University Health Network has grown out of a series of mergers between our current hospitals, as we have adjusted and change to accommodate our growing and changing patient community in and around the GTA.

In 1986, the Toronto Western Hospital merged with the Toronto General Hospital becoming, respectively, the Toronto Western Division and the Toronto General Division of The Toronto Hospital. On January 1, 1998, the Toronto Hospital was amalgamated with the Ontario Cancer Institute/Princess Margaret Hospital, and in April 1999, the name was officially changed to the University Health Network.

On July 1, 2011, UHN integrated with the Toronto Rehab Institute, a move which has physically expanded us to eight locations around the city, and allows us to better serve our patients by bringing together acute hospital care with the rehabilitation care that so frequently follows a hospital stay.

On January 1, 2016, UHN integrated with the Michener Institute, now called the Michener Institute of Education at UHN. This new relationship is the first integration of a health care organization and an educational institution, in Canada. Our integration offers a wonderful opportunity for students in a variety of health professions, just as it offers UHN and all the hospitals which take part in the Michener program, the ability to work with students who will be the future of healthcare in this province.

Our Sites

Each of our hospital sites has its own unique history. Learn more about our sites and how they grew to become a part of UHN.



Altogether, the Hospital may be regarded as the highest development of the modern institution, and the citizens of Toronto have ample reason to be proud of it, as it reflects the spirit of advance to such a marked degree. It is a far cry from the humble beginning made in 1820, and no better illustration of the progress of science and of humanitarianism can be found ... One wonders if the next century will be as full of marvels as the last has been, and whether these hospitals will be as much of an anachronism in 2013 as the old York General would be to-day.
