The earnings and occupational task requirements of immigrants to Canada are analyzed. The growing education levels of immigrants in the 1990s have not led to a large improvement in earnings as one might expect if growing computerization was leading to a rising return to non-routine cognitive skills and a greater wage return to university education. Controlling for education, we find a pronounced cross-arrival cohort decline in earnings that coincided with cross cohort declines in cognitive task requirements and cross cohort increases in manual task requirements. The immigrant earnings outcomes had only a small effect on overall Canadian earnings inequality.
