The American Travel Health Nurses Association mourns the passing of this wonderful man. Please go to our website www.athna.org for our tribute to Jay. He was a champion.

Dr. Keystone was one of the kindest, smartest, most inspiring mentors I had during my training. Even in his last days, when I contacted him with a clinical question, not knowing of his declining health, he responded immediately with nothing but compassion and excellent advice. He was a giant within the medical community, and society at large, as demonstrated by being awarded the Order of Canada. He will be missed by generations of former students and colleagues. My deepest sympathies to his...

My Condolences to Dear Margaret Mascarenhas for your loss of your loving Husband. May god rest his soul in peace

We are so saddened to hear of Jays passing. As a long-time mentor and supporter of U of T students in the Job Shadowing program at Career Exploration & Education, Jay played an important part in helping students navigate and answer their pressing career questions. He instilled them with curiosity and hope. We will miss working with him and wish to send our deepest sympathies to Jay's family and close friend circles.

I am surprised and deeply saddened to hear of the passing of Dr. Jay Keystone. As a final year medical student in 1989, Jay was my ward chief in Internal Medicine in the Bell Wing of Toronto General Hospital. He inspired us to think and act globally. It worked. My career in international health remains to this day, a small tribute to his excellent example and mentorship.
Thank you, Dr. Keystone. You are a deep inspiration. May the family be comforted at this time of great sadness. ...

Dr. Keystone always had time for the needs of even minor travel patients such as myself, and was wonderfully accessible in attitude and in personal warmth. Whatever the situation, he was buoyant and encouraging, with sound advice and a great sense of humour. He lived life joyously, and I feel privileged to have known him.

My Condolences to all the family. He was always an enlightening and entertaining teacher

My condolences to the family. He was a wonderful man

My deepest condolences to Jay's family! He was a dear colleague, who never said no to me when I showed up at his TGH office (unannounced) with a tropical disease question for one of my patients. He had a wealth of information and expertise, and abundant kindness. He will be sadly missed!
