This paper consists of two parts focusing on the immigrant?s decision to acquire Canadian
citizenship, and her subsequent performance as a taxpayer and recipient of public finance
transfers. Our results support the view that selectivity bias appears in Canadian immigrant
citizenship decisions and varies by immigrant gender and source country groups. Our
Oaxaca decomposition results demonstrated the importance of the human capital
endowment in explaining selectivity corrected citizenship -non-citizenship earnings
differences. Next, we confirmed the standard results that the naturalization decision is
conditioned by the expected wage gain , level of education, marital status, age and presence
of children. At the macro level, our study focused on the implications of Canadian citizenship
for the lifetime public finance contributions by naturalized immigrants. All immigrants,
regardless of their source country group and citizenship status, made a positive contribution
to Canada?s treasury circa 1996 over their life cycle. Naturalized citizens from OECD
countries contributed the largest public finance transfers exceeding the corresponding value
for the Canadian -born by more than $14,000. In addition, naturalized citizens made higher
net contributions than their non-citizen counterparts regardless of source country. The
relatively poor public finance performance of non -citizens was explained by their lifetime low
income and low tax payments
