The Canadian population is aging and also becoming more ethnically diverse. This study examined differences in identities among South Asian seniors who immigrated at different life stages with different lengths of residency in Canada. We interviewed 161 immigrants of South Asian descent in Edmonton, Canada, aged 60 and older about their ethnic/national identity, transnational ties, cultural retention and practices, and participation in and concerns about life in Canada. Our findings show that women were more likely than men to see themselves as more South Asian than Canadian. Furthermore, logistic regression analysis showed that older age at immigration and low English-language proficiency were significant predictors of ethnic identity. These findings indicated the importance of language for ethnic and national (Canadian) identity and revealed that South Asian immigrant elders who came to Canada in later life tended to retain their ethnic identities, while immigrant elders who came to Canada earlier in life were more likely to have developed a bicultural identity that incorporated both ethnic and Canadian identity. Related to the notion of bicultural identity, strong transnational ties with the country of origin were associated with greater participation in Canadian society.
