The Graffiti Transformation Project was a City of Toronto, Canada sponsored programme funding ‘marginalised youth’ to paint over graffitied walls with public murals. I argue the imperatives driving the project extended beyond the reaches of policy concentrated on youth remediation, to include concerns of urban governance as a spatial and aesthetic problematic. I explore the manner in which practices of graffiti eradication and community mural making generated a set of calculations that were informed by globally mobile aesthetic norms and were, in turn, aesthetically informing. These calculations were used as an epistemological baseline for assessing, at least at the level of appearance, a host of urban problematics including Toronto’s desire to position itself globally as a functioning multicultural city. Turning to Jacques Ranciere’s thoughts about the space of political aesthetics, I draw on an ethnographic example to tease out a moment of aesthetic engagement in which youth artists interrupted the codes and practices associated with creative city entrepreneurialism to render another configuration of politics, another way of being social. Implications for broadening the scope of urban youth policy scholarship to include analysis of an aesthetic turn are considered.
