Conviviality has recently been taken up to capture everyday living-with-difference in multiethnic cities. Although it has usually been operationalised through an analysis of social interactions framed in neighbourhood or community settings, this article shifts the focus to more tightly delimited public places. Drawing on ethnographic fieldwork in four multiethnic neighbourhood commercial streets in Montréal, Quebec, it proposes a model that unpacks conviviality in place through four components: microplaces, codes of sociability, perceived intergroup relations, and place image (critical infrastructure). The article further argues that while conviviality not only pertains to relations across cultural difference, when it is intercultural, it overlaps conceptually with everyday cosmopolitanism – situated, emergent practices and discourses of openness to, and engagement with, cultural others. It uses the place-based model of conviviality to show how each of the commercial streets has its own distinct variety of everyday cosmopolitanism. Unpacking conviviality in place keeps us attuned to the many dimensions of social relations that make up contemporary cities.
