It is not really up to them to file complaints. The Commissioner of Official Languages reviewed your work, Mr. Head. You got Ds and Es and you are saying that it's up to them to complain. I'm sorry, but it's your responsibility. It is the job of the Department of Public Safety to provide services in both official languages.
When did your action plan start? Was it when the Commissioner of Official Languages carried out the investigation or was it before? How long has the commissioner been reviewing your department for?
