In 2007, people living with HIV/AIDS in Ontario and their service providers created an information system through the Toronto HIV/AIDS Network (THN) to connect people living with and affected by HIV to the services they needed. The service became a provincial website called ASO411, with the support of THN, the Ontario HIV Treatment Network, the AIDS Committee of Toronto, Casey House, Hemophilia Ontario, LOFT Community Services and the Toronto People With AIDS Foundation.

In 2009, CATIE joined the working group and expanded the service across Canada in English and French, with the support of Le Portail VIH/sida du Québec. The website added hepatitis C services in 2013, and rebranded as and in 2014. CATIE assumed responsibility for hosting, promoting and updating the website.
