Missing carbon rebate payment

I’m an international student in Canada and was supposed to receive 3 Carbon Rebate payments. I received the first one without any issues. The second payment was sent as a cheque while I was back in my home country, and at that time I didn’t know about direct deposit.

A friend collected the cheque for me, but unfortunately he lost it while moving to a different house. Later, I set up direct deposit and received my third payment directly into my bank account.

Has anyone been in a similar situation? How can I get the missing second payment reissued or replaced? Do I need to contact CRA and report the cheque as lost?

Any advice would be appreciated. Thanks!
