I don't understand how you could not have received any complaints. It may be because people complain directly to Canada Post, because I know that people are complaining about bilingual service at Canada Post. That agency does receive complaints. Now that it also offers passport service, there must be complaints coming in. Does Passport Canada carry out any follow-up in that regard, to ensure that the terms of the agreement with respect to official languages are being met?
