Opinion: CRA should permit the same delay from calendar year end to RRIF/RRSP withdrawal year end that they do to contributions.

I have to go through more than a dozen account statements for all of 2025, registered and non-registered to try to determine my 2025 tax bracket in order to calculate how much RRIF drawdown I need to do before year end. Why can't this be like contribution time when I have till March 1 and all of my T5's etc have been issued??
