I'm very fortunate to live down the street from Sunnybrook (when house/condo hunting, definitely consider a place close to the hospital). I'm under 30 so I haven't experienced all that Sunnybrook offers, but I am very impressed.
Family Practice Clinic - The staff here are amazing ! My doctor is very thorough and never leaves anything to chance. She is always available and even comes in on her days off. The nursing staff here are great as well ! They genuinely care for all the patients of this clinic. The Reception Team are very friendly, efficient, and organized. They knew that I needed a physical before me. Since it is a teaching hospital, you will have residents with you - having a few set of eyes is better when it comes to your health.
Specialists (Neurosurgery, Dermatology, Gastroentrology, Oncology) - Waiting times to see these specialists are not too long; their staff are very understanding of your concerns and help to speed up the waiting time. I have gone to the Odette Centre a number of times; I was very happy with the medical care.
The most recent medical service I received was surgery. Being that it was my first time, I was very nervous. The nursing staff helped me to relax and not worry too much. I stayed overnight and they came in to check on me often - I was in good hands.
I volunteered here throughout high school; considering doing it again.
Sunnybrook is definitely a 5 +++++ star hospital.
