I am totally find with IRCC asking for an update to my income statement towards the end of my application. I am talking to some companies and hopefully will have a job before too long.RRSP is currently counted towards LICO. I know a few people sponsoring parents who had a small RRSP withdrawal counted towards LICO (both NOA and SIN provided). But that was very small amount. I haven't seen anyone that showed entire year's income as RRSP. At the very minimum, I think this will create doubts in an officer's mind if you will still comply with income requirements the next year so it is likely IRCC will check your income again towards the end of application. But if you will be back to work and will comply with income requirements with regular income, I personally don't see any problem.
