As per CRA: Funds that have been withdrawn under an HBP must be repaid to your RRSP, otherwise, they will be included in your taxable income.
If you fail to make a contribution in any year, it doesn’t increase the future payments’ amounts. The missing payment will be added to line 12900 of your income tax return as an RRSP income. Then, future payments will not be changed. The amount you include on Line 12900 is the minimum repayment amount you have to repay as shown on your HPB statement of account, less any portion you paid. Your HBP balance will be reduced accordingly.
