This paper considers recent efforts to rename and rebrand streets to erase historical oppressors and events in Toronto, Canada. Although renaming campaigns have been common in English-speaking countries, the focus will be on the entanglement of place names and street names, toponymy and odonymy, respectively with not only material sites and infrastructure, but as elements within a broader set of place myths and spatial practices that make up a still-surviving settler colonial matrix and spatialisation. Settler-Colonial Theory argues that genocide of Indigenous occupants and their replacement with settlers, slaves and other labourers was a central feature of colonisation that underpinned rather than followed the rise of capi talism. We begin, however, with an overview of critical toponymy and an outline of Canadian naming practices and policies. These contrast with European practices and display the legacy of changing cultural and political relationships between historically oppressed and hegemonic settler-colonial socioeconomic groups that have controlled the formative development and the last 70 years of planning of Canadian cities such as Toronto.
