Thank you, Mr. Chair.
Thank you, Dr. Ghosh and Dr. Patel, for the work you are doing on the ground.
My first question is for Dr. Ghosh.
Dr. Ghosh, you talked about waste-water testing, and you also talked about two programs that are working very successfully. You're co-chair of the Canadian Network for the Health and Housing of People Experiencing Homelessness. Can you talk about the link between homelessness and substance use? Can you elaborate on that first?
