This post is the latest in a series of articles from guest bloggers. Each week experts and activists in fields of homelessness and mental health explore some of the issues raised by Here At Home.

From NFB interactive, Here At Home is a cutting-edge documentary experience that offers a look inside At Home, a radical experiment to end chronic homelessness. Led by the Mental Health Commission of Canada, the experiment was the largest of its kind in the world. The theory it tested: there’s a way to end homelessness for people with mental illness and it starts with giving them homes.

Because the study recently came to an end, we asked the Chair of the Mental Health Commission, Dr. David Goldbloom to reflect on the project as a whole. Besides his role at the Commission, Dr. Goldbloom is the Senior Medical Advisor at the Centre for Addiction and Mental Health in Toronto and a Professor of Psychiatry at the University of Toronto.

It’s hard to believe that just five years ago, the federal government made a decision to invest in the cause of homelessness among people with mental illness in a major way. And they turned to the newly created Mental Health Commission of Canada to design and run an unprecedented social experiment.

And make no mistake – this was a research study, carefully designed and executed, but one that had the potential to change the lives of the participants and to generate knowledge that could help many more people long after the study came to an end (as it did April 1, 2013).

If you were looking for a justification of the creation of the Mental Health Commission, At Home/Chez Soi was one. Here was a national body – not a federal, provincial or territorial government – who could operate outside of the constitutional framework of health to stimulate and lead an amazing collaboration.
