This study is part of wider research on the history of Arab immigrants in Canada, focusing on the evolution of their identity construction and political activities. What do we know concerning a possible common identity and the political mobilization of immigrants speaking the same language, from the same region – Syria, Lebanon and Palestine – during the first period of Arab settlement in Canada? How did this group of immigrants decide to make their voices heard? Examining ethnic journals published between 1930 and 1950 brings to light traces of community identity construction, association activities, networking dynamics, broader relations with Canadian society and mobilization on political issues.
