Do I attach all my documents and receipts? If so, how do I upload them?

[Sam_Tax]

You do not need to include receipts with your return. Instead, keep them for your records. If the CRA does a pre or post assessment review on these expenses, you will need to have them available to submit as proof. Failure to submit the required documents will result in your claim for that credit or deduction being disallowed.
