<prompt> Human: Recently lost a cheque my mom wrote out to my landlord. We agreed for her to pay my rent now and I will pay her back by the end of the four month lease renting close to where I work. She recently gave me the cheque for the next payment of 475 Canadian dollars. However, it wasnt time to pay the landlord yet so I kept the cheque in my wallet like last time, but like an absolute buffoon I somehow managed to drop the cheque and only noticed it was missing from my wallet after a few days of carrying my wallet around. Ive looked around my room for it and could not find it.Ive already let my parents know and they are furious rightfully so. We arent concerned about the money, the transaction can be reversed once it pops up. However, we cannot put a stop payment on it because we dont know the cheque number.Our 1 concern right now is the possibility of identity theft since a lot of her information is on the cheque. Is it possible and how can we go about this?TL;DR Lost a cheque my mom wrote out to my landlord. Whats the worst case scenario and what can we do to prevent it?Edit: Thanks to everyone who took their time to reply! My dad told me that the cheque is already cancelled. Honestly, he has been more chill about it than my mom, but I understand why they are both angry.Assistant: Honestly, its no big deal. The info on a cheque isnt enough for identity theft - think about it, cheques can be given out to anybody. No compromising info included. In theory, nobody but your landlord should be able to cash it,so it should be fine. If, sometime, your mom gets the cancelled cheque say some random person deposits it then shell have to call the bank and get the fraud department on it, because whoever deposited it is a crook. But most likely, nothing like that will happen. Human: So the information on it alone address, name, bank account number with transit number and institution number isnt enough to apply for a credit card? I didnt think so at first but she freaked out over the phone and now Im really worried.  <response>: So the information on it alone address, name, bank account number with transit number and institution number isnt enough to apply for a credit card?
