The Implications of Sorting for Immigrant Wage Assimilation and Changing Cohort Quality in Canada

Immigrant integration is a central issue in policy debates, with wage assimilation serving as a key indicator of immigrants’ economic success. Using matched employer–employee data from Canada, we study how access to higher-paying firms affects the economic assimilation of immigrants. Immigrants are disproportionately concentrated in lower-paying firms, accounting for much of the observed inequality. Nearly half of this sorting occurs across industries, and both firm- and industry-level wage gaps stagnate after eight years, suggesting that further assimilation reflects human capital accumulation rather than improved firm access. Importantly, these disparities persist after controlling for estimates of worker skill, indicating barriers to high-paying firms rather than differences in human capital. The analysis further shows that Canada’s post-2015 immigration policy reforms significantly improved immigrant outcomes: the initial wage gap narrowed by 25–35%, with roughly half of the improvement attributable to better allocation into higher-paying firms. Taken together, the findings highlight the critical role of firm sorting and its interaction with immigration policy in shaping the economic integration of immigrants.
