The lease agreement that the CRA speaks of is if you were renting a home and signed a lease and had to break it to move. If this wasn't what you did, then you don't need this. If you needed to live in a hotel or elsewhere for a day or two before you got into your new place, then you would need to show the receipts, or you could show a copy of your payment and write beside it what it was for. THe CRA will determine what you can or cannot claim. If you have any specific question, we suggest to reach out to them at 1 (800) 959-8281.
