In this article we examine the economic assimilation of immigrants to
Canada. We provide new evidence on immigrants who arrived in the 1970s
and document an increase in the dispersion of labor market outcomes a
cross immigrants of different vintages over time. Our results confirm
U.S. evidence of ''permanent'' differences across immigrant cohorts. W
hat distinguishes the Canadian experience is small or negative rates o
f assimilation for most cohorts over the sample period. Finally, we te
st the overidentification of the assimilation process specified in pre
vious studies and fail to reject the usual cohort fixed-effect specifi
cation.
