Top 10 RRSP mistakes Canadian investors make in 2026 (cost thousands)

Top 5 RRSP mistakes ranked

1. Over-contributing beyond your room
Canadians can over-contribute by up to $2,000 lifetime without penalty (the "buffer"). Above that: 1% per month on excess.
Example: $8,000 over-contribution stays uncorrected for 6 months: penalty = $8K * 1% * 6 = $480.
Fix: check Notice of Assessment, log into CRA My Account, NEVER contribute more than shown room.

2. Buying high-MER mutual funds inside RRSP
Bank branch sells "TD Comfort Aggressive Growth Portfolio" at 2.20% MER. Vanguard Asset Allocation ETF (VEQT) costs 0.25% MER. Difference: 1.95% per year.
Over 30 years on $50K/year contributions at 6% gross return:
- 2.20% MER: net 3.80% real return: ends with $725K
- 0.25% MER: net 5.75% real return: ends with $1,395K
Fix: switch to ETFs (VEQT, XEQT, VBAL) at one of: Wealthsimple Trade (free), Questrade ($0 ETF), TD Direct, RBC Direct.

3. Forgetting Pension Adjustment (DB plan members)
If your employer DB pension promises 1.5%/year of final pay accrual, your Pension Adjustment for that year reduces RRSP room by approximately that pension value.
For a public-sector employee in DB plan: PA can be $15K+/year, leaving only $5K-$10K RRSP room.
Fix: check Box 52 on T4 slip; CRA Notice of Assessment shows net RRSP room. Do NOT contribute beyond.

4. Missing FHSA opportunity
First Home Savings Account: $8K/year, $40K lifetime, deductible like RRSP, tax-free withdrawal for first home.
Many first-time buyers (especially under 30) still use only RRSP HBP instead of stacking FHSA + HBP.
Fix: open FHSA early - even partial contributions build room.

5. Cashing out RRSP at job change
Leaving a job and "taking the RRSP balance" triggers:
- 10% withholding tax on first $5K, 20% on $5K-$15K, 30% over $15K
- Plus full ordinary income tax on entire balance in that year
- Loss of tax-deferred status forever
Fix: roll over to new employer RRSP, OR open Locked-In Retirement Account (LIRA) for locked-in money, OR transfer to your own RRSP at a brokerage.

Ranks 6-10

6. Not using spousal RRSP for income splitting
Contributing spouse claims deduction; receiving spouse owns account and withdraws.
Useful when one spouse will be in lower bracket at retirement.
For surgeon + homemaker couple: spousal RRSP can save $10K-$30K in lifetime tax.
Fix: use spousal RRSP for the lower-bracket spouse if income disparity is large.

7. Putting US-listed stocks in TFSA instead of RRSP
US withholds 15% on dividends paid to TFSA (no treaty exemption).
RRSP: treaty exemption, NO US withholding on dividends.
Result: a US dividend stock in TFSA loses 15% of dividend yield forever.
Fix: hold US stocks (SPY, JNJ, KO, MMM) in RRSP. Hold Canadian-listed equivalents (VFV, XSP) in TFSA.

8. Missing RRIF conversion deadline at 71
RRSP must convert to RRIF by December 31 of the year you turn 71. Missing this:
- ENTIRE RRSP balance becomes income that year (fully taxable)
- For retirees with $500K-$1M RRSP: catastrophic tax bill
Fix: convert by 71. Minimum withdrawal starts age 72 (about 5.4% rising annually).

9. Skipping employer pension match
Many Canadian employers offer 50-100% match on first 3-6% of salary. Missing this is missing FREE MONEY.
Median missed match for skipped enrollment: $3,000/year on $60K salary at 5%/5% match.
Fix: always enroll in workplace pension to capture full match. Make additional RRSP contributions on top.

10. Withdrawing from RRSP in high-income year
RRSP deduction was meant to defer tax to a lower-income year. Withdrawing in your peak-earning years:
- Pay tax at top marginal rate (53.53% in Ontario, 46.30% Quebec)
- Defeats the entire point
Fix: do NOT withdraw from RRSP except for retirement, HBP, or LLP. Use TFSA or non-registered savings for working-year cash needs.

Common RRSP-vs-TFSA confusions

Many Canadians get confused about which to use. Quick decision framework:

Worked retirement income examples

Scenario A: typical Canadian, age 30 to 65 RRSP build-up
- $60K average salary across career
- Contributes 10% to RRSP ($6K/year)
- Real return: 6%
- 35 years contributions
- RRSP at 65: $710,000
- At 65: convert to RRIF, 4% withdrawal: $28,400/year
- Plus CPP at 65: $17,200
- Plus OAS at 65: $8,724
- Total income: $54,000/year (taxable, ~30% effective rate = $38K net)

Scenario B: high earner, age 30 to 60 RRSP + TFSA
- $150K average salary
- Maxes RRSP ($32,490 + carry-forward) + TFSA ($7K) annually
- Real return: 6%
- 30 years contributions
- RRSP at 60: $2.8M
- TFSA at 60: $580K (tax-free)
- Total tax-advantaged: $3.4M
- 4% withdrawal: $136K/year + $23K tax-free TFSA = $159K combined

Scenario C: late starter, age 50 to 65
- $80K average salary
- Maxes RRSP ($14K) + TFSA ($7K) for 15 years
- Real return: 6%
- RRSP at 65: $330K
- TFSA at 65: $165K
- 4% withdrawal: $13.2K + $6.6K + CPP $17.2K + OAS $8.7K = $45.7K/year

Scenario D: business owner using LCGE
- Maxes RRSP + TFSA + builds business value
- Sells business at age 60 for $1M
- LCGE shelters first $1.016M of gain (full shelter)
- $1M cash at age 60 used for personal investment + lifestyle
- Plus accumulated RRSP/TFSA = robust retirement

Scenario E: stay-at-home parent + working spouse
- Spousal RRSP funded by working spouse (deduction at 53.53% marginal)
- Spouse withdraws after retirement at, say, 30% marginal
- Tax shifted from 53.53% pocket to 30% pocket
- Net family tax saved: $5K-$10K per $50K transferred

Avoiding the 5 most expensive errors

Quick checklist for Canadian retirement saving:

1. Get pension on your radar:
- DB pension member: ask HR for PA estimate, calculate net RRSP room
- DC pension: ensure you contribute enough to capture FULL employer match
- No pension: prioritize RRSP + TFSA

2. Choose right account at right time:
- 18-30: TFSA + FHSA (if first-time buyer) + workplace pension
- 30-50: RRSP max + TFSA max + FHSA closing
- 50-65: RRSP + TFSA + retirement projection refinement
- 65-71: convert RRSP to RRIF for pension income splitting (can do at 65, not just 71)
- 71+: RRIF mandatory withdrawals, plan tax

3. Use right brokerage:
- Wealthsimple Trade: commission-free, no minimum, ETFs only
- Questrade: $0 ETF buying, robust
- TD/RBC/BMO/CIBC Direct: full-service, $9.99 trades, broader research
- AVOID: bank branch mutual funds with 2-3% MERs

4. Diversify globally:
- Canadian-listed ETFs: VEQT, XEQT, VBAL, XBAL (for asset allocation)
- Or build manually: 40% US (VFV/XSP), 30% Canada (VCN/XIC), 20% Int. dev. (VIU/XEF), 10% emerging (VEE/XEC)

5. Plan withdrawal sequence:
- TFSA last (tax-free indefinitely)
- Non-registered: harvest capital losses each year
- RRSP/RRIF: withdraw to fill marginal bracket up to clawback thresholds
- CPP + OAS: claim at age that aligns with break-even math

6. Annual checkup:
- Each March: review RRSP/TFSA room used, contributions for upcoming year
- Each April: review tax-loss harvesting opportunities, capital gain triggering
- Each December: rebalance portfolio if needed
- Each year: update RRSP contribution timing if income changes
