My passport went through the wash (and dryer) I used it for a year or so after that before it raised a few too many comments at customs. I sent it back with all of the documentation necessary, (I thought). Turns out as the passport was valid yet damaged I had to fill in another form and have it witnessed in front of a notary or lawyer stating how it became damaged etc. When I eventually received my new one it states on one of the pages "This Passport replaces a valid, damaged Canadian passport” I will take better care of this one!!
