Addiction Impacts Many. We Believe Addiction Support Should Too.
In Ontario, 1 in 10 will deal with substance addiction at some point in their lives, and many lack access to the support and resources needed for treatment and recovery. The Annex is a St. Thomas addiction resources centre dedicated to helping individuals address their substance abuse in a safe, compassionate, and non-judgemental environment.
The Annex provides services at no cost, because we believe that all people deserve respect, support, and access to care and treatment.
