HI Guys I'm just tracking my mail sent to Fort Erie and it says like this "Attempted delivery. Notice card left indicating where item can be picked up" I shouldn't mail it with SIGNATURE REQUIRED do you think guys that somebody will gonna pick up my letter to Canada Post? I tried phoning Canada POst to let them drop my letter to the PO Box but they said they can't do that. They said I'll wait and see if somebody will pick-up or not. DO YOU THINK IMMIGRATION CANADA CENTRE MAILMAN WILL CARE TO PICK-UP MY LETTER/APPLICATION? I shouldn't mailed it that way. Anyone who experience like this? DId your mail reach Buffalo with a letter that requires signature? Thanks a lot. It worries me now. I hope my passport won't be lost.
