Yes, the journals normally receive funding from the Social Sciences and Humanities Research Council of Canada. However, those journals aren't required to be truly bilingual to receive it.
More effort has been made at certain times, but no longer now. That could be changed. For example, a directive could be sent to various so‑called bilingual journals encouraging them to publish more articles in French in order to deserve their funding. They could also be asked to show us how to meet the bilingualism requirements of the next Official Languages Act.
