up" the neighbourhood by dispersing its close-knit residents. Successful resident-led initiatives to improve conditions in the DTES include the transformation of the then-closed Carnegie Library into a community centre in 1980, the opening of an unlicensed supervised injection site in 2003, which led to the founding of Insite; improvements to Oppenheimer Park, and the creation of CRAB Park. In 2010, the V6A postal area, which includes most of the DTES, had the second-highest concentration of artists in the city. Artists made up 4.4% of the labour force, compared to 2.3% in the city as a whole. The Downtown Eastside Artists' Collective was formed by Trey Helten, manager of the Overdose Prevention Society. The greater DTES area is the location of several art galleries, artist-run centres and studios. Prominent local artists include poet Henry Doyle, artist Marcel Mousseau, and poet Bud Osborn. Notable annual events include the Downtown Eastside Heart of the City Festival, which showcases the art, culture, and history of the neighbourhood, and the Powell Street Festival in Oppenheimer Park, which celebrates Japanese-Canadian arts and culture. The Smilin' Buddha Cabaret operated at 109 East Hastings Street from 1952 to the late 1980s as a symbol of "cultural vitality," reflecting shifts in the neighbourhood itself. City Opera of Vancouver, the Dancing on the Edge Festival, and other artists regularly perform in DTES venues such as the Carnegie Centre, the Firehall Arts Centre, and the Goldcorp Centre for the Arts at the Woodward's site. The musical composition, "100 Block Rock," featuring 11 tracks, was released in 2020. In 2010, Sam Sullivan, former mayor of Vancouver, said that in the DTES, "Behind the visible people who clearly have a lot of troubles, there's a community. Some very intelligent people say this is the cultural heart of the city." Current issues Addiction and mental illness The DTES population suffers from very high rates of mental illness and addiction. In 2007, Vancouver Coastal Health estimated that 2,100 DTES residents "exhibit behaviour that is outside the norm" and require more support in the areas of health and addiction services. According to the Vancouver Police Department (VPD) in 2008, up to 500 of these individuals were "chronically mentally ill with disabling addictions, extreme behaviours, no permanent housing and regular police contact." As of 2009, the DTES was home to an estimated 1,800 to 3,600 individuals who were considered to be at "extremely high health risk" due
