Retirement income surprises are usually stacking problems, not single-account problems.
A pension, CPP, OAS, RRIF withdrawals, and non-registered income can each feel manageable individually. They don't arrive on separate returns, though. They land together, on the same line, in the same year.
The useful shift is moving from planning year to year for cash flow, to modelling what total taxable income looks like once every source is active at once.
Before your next withdrawal decision, ask: if every income source I expect were turned on today, what would my total taxable income actually be?
If you haven't added them all together yet, that's the number to check before defaulting to the easiest option.
