I have claimed CCA again my Self Employment and yet I am not seeing any changes to the Refund. Am I doing something wrong?

CCA is a deduction from your self-employment income, not a tax credit. That means it reduces the amount of your income that is taxable. So, if your taxable income is already very low, then the CCA deduction may not make a big difference to your return.
