Retiring in Ontario
Your encore years, Ontario edition.
Ontario adds two things most other provinces don't: a surtax on top of provincial tax once it passes a threshold, and the separate Ontario Health Premium — both of which show up as a bigger bite than the posted bracket rates suggest.
- The Ontario surtax is tax-on-tax — a percentage of provincial tax itself once it crosses a threshold, so it compounds with bracket creep rather than sitting alongside it.
- The Ontario Health Premium is a separate income-tested levy on top of regular tax, calculated on your total income, not your tax bill.
- Ontario's surtax and Health Premium thresholds are treated as fixed in this model (not indexed) — over a multi-decade retirement, that's a slow tightening worth stress-testing, not a one-time cost.

When should you start CPP and OAS?
CPP and OAS are federal, but the tax rate you'd pay on them isn't — this sweep uses Ontario's brackets to find the start ages that leave you with the most, after tax.
These are single-year, single-scenario checks. For a full Ontario retirement plan — CPP/OAS timing, RRIF minimums, a second person, and the after-tax estate your plan actually leaves behind — build your full plan, free.
