Although not fully conceptualized as such by geographers, children and concepts of childhood were focal points of colonialism. Well into the twentieth century, Aboriginal peoples in Canada were discursively constructed by colonists as child-like subjects in need of colonial intervention in order that they ‘grow up’ into de-Indigenized Canadian citizens. Further, an important aspect of the colonial project entailed confining Aboriginal children in institutions known as Indian Residential Schools wherein, through material and curricular means, efforts were made to transform the children and dispossess them of socio-cultural identities. Much of the literature on children's geographies contemplates the socially constructed nature of childhood and critiques the pervasive (yet under-evaluated) understanding that childhood is a clear and demarcatable state of being prior to adulthood. Little attention, though, has been paid to historic or social discourses that relegated groups of people to a perpetual state of truncated childhood while simultaneously removing their children in order that those children mature into adults who embodied radically different cultural traits than their ancestors. This paper explores how Aboriginal peoples were doubly confined; firstly, by colonial constructions about children, childhood, and Othered (Aboriginal) peoples and then, secondly, within the material geographies of colonial residential schools.
