In this paper, we provide a comprehensive picture, circa the late 1980's, of occupational gender segregation in Canada and its consequences for wages. Our analysis reveals sensitivity of the estimated penalty to female work to both specification and estimation strategy. Our preferred estimates indicate that the wage penalties for women in female jobs in Canada are generally smaller than penalties in the United States. Of particular note, while there is some heterogeneity across worker groups, on average the link between female wages and gender composition is small and generally not statistically significant.
