I'd like to add a brief comment.
The conclusion seems to be that this lack of complaints stems from poor knowledge of rights. However, that's an opinion. I'm not sure the Office of the Commissioner has specific figures that could support that fact.
I can say that, in my 10 years dealing with language rights at the Department of Justice, to my knowledge, we only had to handle a single complaint concerning the question of access, and it involved the Attorney General of Canada, whether it was before criminal courts or civil courts.
We're making efforts to increase litigants' awareness back home. The Office of the Commissioner of Official Languages has a mandate to make the public aware of their language rights. We must definitely continue making efforts in that area.
However, before drawing any negative conclusions about the lack of complaints, perhaps we should rethink this process somewhat.
