By 1981, the Centre assumed on-going responsibility for youth with a dual diagnosis for all of Toronto. Late in that same year, the Centre opened an intensive residential treatment program for these youth, the first of its kind in Canada.

The Centre grew rapidly and steadily. In 1983, it was officially re named the "J. D. Griffin Adolescent Centre,” in honour of Dr. Jack D. Griffin, one of the Canada's most distinguished leaders in the field of community mental health.

The 1990’s brought an expansion into adult services resulting in a number of partnerships with other agencies, both in the Mental Health and Developmental Services Sectors to provide services to dually diagnosed adults.

Today, we are known as Griffin Centre. We employ more than 180 staff and offer over 30 essential programs and services in Toronto for vulnerable youth and adults with mental health challenges and/or developmental disabilities and their families.
