Estate tax obligation — running exposure
If the last surviving spouse died in a given year, the income tax the estate would owe — mainly the deemed disposition of registered accounts (RRSP/RRIF + LIRA/LIF), plus non-registered gains and any business. The shaded band is ages 60–70, where large registered balances create the biggest exposure before draw-down.

Recommended withdrawal plan — stay in the lowest bracket
Each retirement year: where the after-tax spending should come from to keep taxable income low. The engine fills cheap tax-bracket room from registered accounts (up to your target), then draws tax-free from TFSA, then non-registered — pushing into higher brackets only when unavoidable.
