Super visa Income requirement proof

[toronto_12]

Hello everyone. In the past my mother was granted super visa twice and her recent super visa expired now. Im applying for her again. My annual income for past few years always higher than income required for super visa but i changed my job a month ago and now im on salary plus commision. In total salary plus commision i can easily make more than last few years but if i submitt employment letter it will show salary which is less than required plus commion which is not earned yet. i went through official website they ask for different document as proof of income like NOA , employement letter, t4, pay stubs etc. I can easily provide my last year NOA in which my income is way beyond required income do i still need to provide letter of employment or my last year NOA will be enough proof of my income. please guide

Last year's NoA is enough, that's the main proof of income document.
