Meltdown plan

59M single retired with 2.5M in RRSP. Income from dividend in RRSP is 80K per year. Planning to delay OAS and CPP to 71. I don’t know how fast I should withdraw from RRSP to minimize crawl back. Considering withdrawing 150K annually and put any extra that I didn’t spend to TSFA or non reg. If I withdraw more per year, it will put me in higher tax bracket. Not sure if there is any advantage. Any other suggestions?
