The Economic Returns to the Knowledge and Use of a Second Official Language: English in Quebec and French in the Rest-of-Canada

Knowledge of an additional language may be associated with enhanced earnings because of its actual value in the workplace, or its value as a screen for ability. Previously available data did not indicate whether bilingualism was actually practiced. The 2001 Census reports, for the first time, the primary and secondary languages used at work. Conditioning on both language knowledge and language use determines the additional earnings that can be attributed to the use of a second official language. We find substantial, statistically significant, rewards to second official language use in Quebec and insignificant effects in the Rest-of-Canada.
