Leah Montange is a human geographer living and working in Toronto. She researches and writes about borders, detention, prisons, and the political, social, and economic relations that produce them. She also writes about and for people who resist carceral relations. Her work addresses the relations between human life and state power in contexts of bordering, detention, and labour — contexts where freedom, unfreedom and mobility are at stake. Her work is published in Citizenship Studies; Environment and Planning D: Society and Space; the Annals of the Association of American Geographers; Globalizations; ACME: An International Journal of Critical Geographies; Society and Space; and Population, Space and Place. She teaches courses on borders, cities, labour, citizenship, migration, and transnational space. Leah also recently taught with the Freedom Education Project Puget Sound and has long participated in abolitionist organizing in WA State in the US.
