Canada Post Mailbox locations

I'm not sure why, but I was trying to find a map of mailbox locations one day. I expected to find it on the Canada Post website, but apparently not. But I did find a Google maps that someone created. See it here. It is obviously not complete, but if you know of a mailbox location or two, add it! The creator left it open for everyone to add too. I know it has become a recent obsession of mine to try to find as many locations in my area as possible.
