Financial Independence, Retire Early (FIRE) is built on a simple premise: save 25 times your annual expenses, withdraw 4% per year, and your money lasts indefinitely. But this framework, developed primarily from US data, needs significant adjustment for Canadian investors — particularly because of CPP, OAS, and our tax system.
The 4% Rule: What It Actually Says
The 4% rule emerged from William Bengen's 1994 research analyzing US market data back to 1926. He found that a 4% annual withdrawal rate from a balanced portfolio had never been depleted over any 30-year historical period.
Critical limitation: The research was based on US market returns and a 30-year horizon. A Canadian early retiree at 40 may need a 50-year horizon — suggesting a safer withdrawal rate closer to 3.25–3.5%.
The Canadian FIRE Number Adjustment
CPP and OAS significantly reduce the portfolio needed to sustain retirement.
Annual spending: $80,000 | CPP for two at 65 (average): $17,600 | OAS for two at 65: $15,000
Portfolio gap after 65: $80,000 − $32,600 = $47,400/year
FIRE number: $47,400 × 25 = $1,185,000 (vs $2,000,000 without CPP/OAS)
Saving: $815,000 in required portfolio
CPP/OAS Benefits in 2026
| Income Source | Maximum at 65 (2026) | Average Canadian Benefit |
|---|---|---|
| CPP | $15,300/year | ~$8,800/year |
| OAS | $8,470/year | ~$7,500/year |
| Combined maximum | $23,770/year | ~$16,300/year |
FIRE Variants Explained
| FIRE Type | Target Portfolio | Lifestyle |
|---|---|---|
| Lean FIRE | $500K – $800K | Very frugal, minimal spending |
| Regular FIRE | $1M – $1.5M | Comfortable, same lifestyle |
| Fat FIRE | $2.5M+ | Travel, dining, no sacrifice |
| Barista FIRE | $400K – $800K | Part-time work supplements savings |
| Coast FIRE | Enough to grow to target | Work to cover expenses only |
Early Retirement Considerations in Canada
CPP Impact of Early Retirement
If you stop working before 60, your CPP entitlement may be significantly below the maximum. CPP is based on your contributory earnings during your working years. Check your actual projected benefit at Service Canada My Account.
Provincial Health Coverage Advantage
Unlike the US, where pre-65 retirees need to purchase private health insurance (often $500–$1,500/month), Canadian provincial health insurance covers most medical costs indefinitely. Budget $2,000–$5,000/year per person for dental, vision, prescriptions, and paramedical services not covered provincially.
