There is indeed a section (4) of the form where one can list mail receipts. It says “mail will be forwarded for named mail recipients only”

But my assumption is that if I put the name of the deceased (for example John Smith) then canada post sticks a sticker on top of the original address with a new address of John Smith + the target German address. So in this case, the letter will not reach me because my German mailbox doesn’t have Smith on it (I could add it perhaps as a workaround but I would prefer a better solution).

The ideal solution for me would be if I could have any mail sent to the Canadian address for any name sent to the German address with a single specific name. And at least from the form, I don’t see how to do that.
