Barb Collins


Barb Collins was appointed the President & CEO of Humber River Hospital in Toronto, Canada, on July 1, 2016. Ms. Collins is a Registered Nurse, with an MBA from Queens University in Kingston, Ontario. She has more than 35 years’ experience in all major clinical and management functions of an acute care hospital, including Intensive Care, Emergency, Obstetrics, Operating Room, Surgery, Inpatient Care and Support Services.

Prior to assuming her current responsibilities as President & CEO, Ms. Collins served as the hospital’s Chief Operating Officer. As COO, she was the senior Executive Lead for Humber River Hospital’s redevelopment project, Ms. Collins was charged with overseeing the design, construction and activation of the new Humber River Hospital. This 656 bed, 1.8M square-foot acute care facility provided Humber with a unique opportunity to optimize design, incorporate technology and reinvent processes to deliver more effective and efficient patient-centred care, supported by some of the world’s finest medical technology.


The result is North America’s first fully digital hospital, groundbreaking in its approach to integrating technology across all hospital systems and workflows. At HIMSS 2016 in early March, the Intelligent Hospital Association presented Ms. Collins and other senior Humber River executives with a Special Recognition Award, recognizing the hospital’s ‘demonstrated leadership in the digital health community’.


The new Humber River Hospital opened for patient care on Sunday, October 18, 2015.
