This study revealed that more than 15% of immigrants admitted to Canada from 1982 to 2017 emigrated within 20 years of admission. However, this proportion varies by characteristic, including immigrants' country of birth.
Emigration is slightly more common from three to seven years after admission. This period may reflect the length of time that immigrants try to integrate into Canada by attempting to find a job and a place to live and adapting to life in Canada. Some immigrants may also emigrate if they encounter challenges in integrating or because they intended to from the outset.
Immigrants born in Taiwan, the United States, France, Hong Kong or Lebanon and immigrants admitted in the investor and entrepreneur categories are more likely to emigrate.
Longitudinal Immigration Database data will continue to be used to analyze the socioeconomic situation of immigrants, including economic integration and retention in the province or territory of admission.
