This article examines the social construction of migrant labour forces through an analysis of the exterior and interior conditioning in an agricultural contract labour programme between Mexico and Canada. I argue that forms of exterior conditioning, especially employers' point-of-production control, establishes the context within which migrant workers' experience unfolds, for which reason it contributes to their 'interior conditioning'. But I argue as well that the result is shaped by workers' employment of a 'dual frame of reference' through which they gauge Canadian wages and working conditions the only way they can, which is in relationship to Mexican ones. Given that neoliberal policies have reduced the options available in Mexico, and diminished the attractiveness of those that remain, contract labour in Canada presents one of the few opportunities many poor, rural Mexicans have to acquire the income necessary for a minimally dignified life. Consequently most workers in this programme do everything possible to please their employers and continue in the programme.
