History of The Princess Margaret


Princess Margaret Cancer Centre was first established as the Ontario Cancer Institute in 1952 by the Ontario government. Originally located at 500 Sherbourne Street in Toronto, the institute was officially opened on May 1, 1958 by Her Royal Highness the Princess Margaret and was re-named Princess Margaret Hospital to mark the occasion.

On November 13, 1995, Princess Margaret Hospital moved to its current location at 610 University Avenue, in the heart of Canada’s innovation hub and within the greatest concentration of teaching and research hospitals in the country. Her Royal Highness, Princess Margaret was there once again to officially re-open the 130 bed cancer hospital on July 12, 1996.

In 1998, the Princess Margaret Hospital became part of the University Health Network (UHN), merging the oncology services of Toronto General and Toronto Western hospitals with those of Princess Margaret, making Princess Margaret Hospital the largest comprehensive cancer program in the country.

In 2012, Princess Margaret Hospital was renamed the Princess Margaret Cancer Centre to reflect its specific focus on cancer research and cancer care. Today, The Princess Margaret is one of the top 5 cancer research centres in the world.

In 2018, work began on the Transformation of Princess Margaret Cancer Centre to be funded through an ambitious $50 million capital campaign.  The work has begun and is expected to be completed in 2019. This multi-phased project includes the transformation of the main floor to improve the experience of patients from the moment they step through the door. We are also building Cancer Center capacity for the future putting our patients needs first. The project includes the creation of a new Gynecologic Oncology Clinic, which is now open on the 5th floor, and our first-ever Outpatient Palliative Care clinic that opened in August 2018. The work continues on the main floor to transform the outpatient pharmacy and book collection centre, an enhanced patient library and patient lounges and a digitally-enabled hub and Foundation space.  For more information about our Transformation Campaign click here
