Do I need to have receipts for all purchases made as eligible supply expenses as a teacher?

I know I have spent up to $1000 but I do not have paper receipts of purchases that I have made for my classroom.

Receipts are needed in case the CRA asks for them. If you are not able to provide receipts, they may ask you to pay back the credit.

 

The receipts can be digital, if you weren't given a paper receipt.
