Note that one is clearly better off, return wise, with the non-RRSP investment until approximately 13 years has passed. Cashing out RRSPs earlier than 13 years is financially stupid.
And the two curves pretty much remain fairly converged after 13 years, which means you are not really extracting a premium for locking up your equity within the RRSP. Whereas, if you kept the equity outside of the RRSP, you could be using it to lower your cost of credit insofar as borrowing is concerned, and you could be applying leverage to your investments.
Of course, one is far worse off with the RRSP if they are paying a higher effective tax rate in the withdrawal phase than they were paying in the accumulation phase.
So aside from the short-term pyschological effect of saying 'up yours' to the taxman, there is little reason to accumulate anything but fixed income investments in a RRSP. And even then, if one has a mortgage, they shouldn't be buying fixed income anyways -- they should be merely paying down their mortgage, as it doesn't make sense to be simultaneously a lender, and a borrower, when borrowing costs significantly more than the returns on lending (due to varying credit spreads, or a flat/inverted yield curve).
edit: the graph also proves my other point, that only people in their 30s and early 40s should consider investing in RRSPs at all, over and above amounts that can be withdrawn under the HBP/LLP. If you invest in a RRSP when too young, you've locked up your money for all those years for no additional return (as the curves completely converge after 40 years anyways). If you invest in a RRSP when too close to retirement, you never do achieve the advantage of the tax deferral inside the RRSP.
a further note: non-RRSP savings can be accumulated in tranches, and removed on a LILO basis, highest cost-base first, so as to maximize long-term tax deferral, whereas no such optimization is possible on a RRSP. Borrowing can also be used to defer tax until death. This is not possible with RRSPs/RRIFs in the withdrawal phase.
