Lorna Montgomery began her career as an Occupational Therapist and Physiotherapist and quickly moved into a leadership role as Manager of the Mississauga Infant Stimulation Program in 1976. She also helped develop the Humber-Guelph Infant Stimulation Program. These two programs merged in 1978 and became Infant and Child Development Services Peel (ICDSP), which Montgomery managed for nearly 40 years until she retired in 2017.

Montgomery is recognized locally, nationally and internationally as a pioneer in the field of early intervention. In 1980, she helped found the Ontario Association for Infant and Child Development (OAICD). In 1994, under her leadership, the OAICD established best practice guidelines for the province. Montgomery recognized the innovative work being done in Ontario and presented at Early Intervention Conferences across Canada, International FASD Conferences, Zero to Three, and conferences hosted by the International Society of Early Intervention. 

She was a valued partner in Humber’s Early Childhood Education department for more than 30 years, and a member and chair of the Program Advisory Committee from 2000 to 2015. She’s been recognized for her accomplishments with the Community Caring Award, the Mary Neville Award and the OAICD Long Standing Service Recognition Award, among others.

Montgomery led the creation of the Preterm Care Pathways, Preterm Substance Exposure framework and the Peel diagnostic FASD team. When she retired at the age of 70, the Early Childhood Education field lost a precedent-setting advocate for infant and child development early intervention services.
