This article makes a contribution to the field of French immersion studies by examining the engagement realities of two groups of students in an Ottawa French immersion high school program: those with and without a parent who makes them eligible for minority French language instruction as outlined by Section 23 of the "Canadian Charter of Rights and Freedoms." Findings indicate that students from both official language groups, who came from varying class backgrounds, similarly demonstrated the ability and willingness to follow the secondary French immersion program offered at the university level. Although students with Anglophone parents were found to benefit from cultural capital such as family support and "voluntary minority" belief systems, students with a parent eligible for minority French language instruction benefited from French language capital acquired with family, in social contexts and sometimes in French school. At times, students also had overlapping and cross-cutting realities depending whether they came from EFI or LFI programs. To conclude, this article suggests that French immersion programming and related policies should take into consideration the multifaceted engagement realities of secondary student populations from the two official language communities.
