Reporting Lost Non-Tracked Mail to Canada Post

So today I learned that there is a formal method to report lost non-tracked mail (such as lettermail) to Canada Post. Unfortunately, there is no fast an easy way to do this online. If it were a tracked item, you could open a ticket online via the Canada Post website, but for non-tracked items there's no such luck. However, I found that you can call Canada Post customer service (1.800.267.1177) and they will officially record the matter and give you a reference # regarding the issue. I was hoping they would record where the item was dropped off (location of Canada Post depot) but they only record the recipient postal code. So they'll maybe catch trends of mail lost at the distribution center used for the recipient but, unfortunately, will never catch any trends of employees loosing/stealing mail where it was dropped off. Ah well, better than nothing. So, if mail continues to get lost on route to the same locations you can call back Canada Post with your list of reference #'s and request that some action take place. Hmmmm.... I wonder if any action actually would take place in that scenario??? Otherwise, they claim they'll simply use the reports to improve their services.
