This paper examines the challenges migrant groups that are new and internally diverse face to participate and build community in host societies today. Qualitative research findings on Latin American migrants' experiences in Toronto, Canada, reveal that the group's participation is the result of a complexity of social and spatial processes. The paper contributes to current debates on the study of immigrant integration in three ways: (1) by focusing on immigrants' collective forms of organising, (2) by responding to ongoing calls for a closer examination of intra-group diversity, and (3) by drawing on transnationalism research to avoid the use of essentialising categories in the study of immigrant groups that are internally diverse. © 2010 Springer Science+Business Media B.V.
