Expected annual return

TFSA and RRSP (pocket the refund) both cost $6,700/yr out-of-pocket — a fair apples-to-apples comparison. RRSP + reinvest requires saving your $3,300/yr refund too ($10,000/yr total), which is why it always leads. Actual results depend on contribution room. Not financial advice.

RRSP + reinvest refund wins

Contributing $10,000/yr to RRSP and reinvesting the $3,300/yr refund into TFSA leaves you $161,857 ahead of TFSA-only after 20 years. Note: this strategy saves $3,300/yr more than the other two (total annual savings $10,000 vs $6,700).
