This is a topic that seems a bit nuanced so is best to be discussed with a tax professional. RRSP withdrawals though do not qualify for the pension income tax credit. That's why when an investor turns 65, it's often better to convert all or a portion of their RRSP or RRIF to get tax savings of $2,000 on retirement income. RRSP splitting is allowed, it just may not be the best approach, depending on one's own tax circumstances. This link will provide some colour.
