On their website, they mention two funding agencies. I believe that these are your department and the Mental Health Commission of Canada. It seems to me that it would be reasonable to ask this commission to provide services in French.
You keep saying that everything is done in French and English at the same time. However, the Commissioner of Official Languages and others besides me have found gaps. Earlier, for example, the Public Service Alliance of Canada said that it was very difficult to operate in French in Quebec.
Unless you are the exception that proves the rule, you must find that there are challenges in providing services in French. I'd like to hear what you have to say about that.
