The Migrant Worker Solidarity Network and the Canadian Centre for Policy Alternatives, Manitoba have released Migrant Voices: Stories of Seasonal Agricultural Workers in Manitoba. 

Migrant Voices is based on interviews conducted with migrant farm workers in Manitoba during the summer of 2011. About 400 workers come to Manitoba every year, mostly from Mexico, to plant and harvest much of the produce grown in Manitoba.
