The same pre-tax dollars, two shelters. The whole question turns on one comparison: the tax rate today versus the tax rate in retirement. Rates equal, the two come out identical to the cent — that’s the structural identity this page proves — and every real answer is just that comparison tilted one way or the other.
Where the registered accounts end and the balance sheet begins — large financing, structured around the plan — is where this desk comes in, alongside you.

Illustration only — not investment or tax advice. The fair pre-tax framing assumes the RRSP refund is reinvested; a spent refund tilts the result toward the TFSA. Ignores contribution-room limits (the accountant tracks the client’s actual room), employer matches, the RRSP’s age-72 conversion rules, and income-tested benefit clawbacks in retirement — real files weigh all of these. Annual contributions at year-end, constant return, one tax rate per period. Clients should confirm with their own tax and investment advisors.
