Bonds are boring. That's the point. Here's when you need them and which funds are worth owning.
Bonds reduce portfolio volatility. In a year where stocks drop 30%, a portfolio with 40% bonds might drop 15% instead. That's the deal: you accept lower long-term returns in exchange for sleeping better at night.
You probably need bonds if:

The Couch Potato approach has model portfolios from conservative (60% bonds) to aggressive (0% bonds). Pick the one that matches your actual risk tolerance, not your aspirational one.
These are the core bond funds most Canadian investors should consider. All hold investment-grade Canadian bonds — government and corporate.
| ETF | Provider | MER | Yield | Duration | Holdings | AUM |
|---|---|---|---|---|---|---|
| ZAG | BMO | 0.09% | ~3.5% | ~7.3 years | ~1,600 bonds | $9B+ |
| XBB | iShares | 0.10% | ~3.5% | ~7.5 years | ~1,600 bonds | $6B+ |
| VAB | Vanguard | 0.09% | ~3.5% | ~7.4 years | ~1,200 bonds | $4B+ |
| ZSB | BMO | 0.10% | ~4.0% | ~2.8 years | ~700 bonds | $2B+ |
| XSB | iShares | 0.10% | ~3.8% | ~2.7 years | ~500 bonds | $1B+ |
| CLF | iShares | 0.10% | ~3.2% | ~12 years | ~600 bonds | $2B+ |
For most people: ZAG or VAB. They track the same index (or very similar ones), have near-identical MERs, and will deliver nearly identical returns. Pick whichever your brokerage makes convenient. ZAG is slightly more liquid (higher AUM).
Yield is the income the bond fund pays — the coupon payments divided by the price. A 3.5% yield on a $10,000 bond fund gives you ~$350/year in distributions.
Duration measures interest rate sensitivity. A fund with 7-year duration drops ~7% in price for every 1% rise in interest rates. When the Bank of Canada raised rates aggressively in 2022-2023, ZAG dropped ~15% from peak to trough.
Duration ~2.5–3 years. Less sensitive to rate changes — when rates rise, you lose less. When rates fall, you gain less. Better for stability.
Best for: money you need in 2–5 years, conservative investors, or when you expect rates to keep rising.
Duration ~7–8 years. The standard Couch Potato bond holding. More volatile than short-term, but higher long-term expected returns.
Best for: long-term balanced portfolio allocation, the bond portion of a 60/40 or 80/20 portfolio.
The 2022 lesson: Bond funds can lose money. ZAG dropped ~11% in 2022 when rates spiked. If you panicked and sold, you locked in losses. Bonds aren't risk-free — they're lower risk than stocks. There's a difference. The rate hike cycle also increased yields, so bond returns going forward look better than they did in the 2010s.
| Bond ETF | MER | vs | Bond Mutual Fund (Example) | MER |
|---|---|---|---|---|
| ZAG (BMO Aggregate Bond) | 0.09% | vs | RBC Bond Fund (Series A) | 1.38% |
| XBB (iShares Core Bond) | 0.10% | vs | TD Canadian Bond Fund (Investor) | 1.37% |
| VAB (Vanguard Aggregate Bond) | 0.09% | vs | CIBC Canadian Bond Fund | 1.40% |
Paying 1.38% to hold bonds yielding 3.5% means the fund company takes 40% of your income. On $50,000 in bonds, that's $690/year in fees versus $45. The MER fee drag on bond funds is proportionally worse than on equity funds because the returns are lower.
TD's e-Series Canadian Bond Index (TDB909) at 0.50% is the cheapest mutual fund option. Still 5× more expensive than ZAG, but usable if you prefer mutual funds for automatic purchases.
For the fixed-income portion of your portfolio, bond funds aren't your only option:
| Product | Return | Risk | Liquidity | Best For |
|---|---|---|---|---|
| Bond ETF (ZAG) | ~3.5% yield | Can lose value | Sell anytime | Portfolio allocation, rebalancing |
| GIC (1-year) | ~3.5–4.25% | Guaranteed | Locked | Money you won't need for 1+ years |
| HISA | ~2.25–3.50% | Guaranteed | Instant | Emergency fund, short-term |
| HISA ETF (CASH.TO) | ~4.50% | Minimal | T+1 | Cash in brokerage accounts |
GICs beat bond ETFs when you're certain you won't need the money and rates are attractive. Bond ETFs win when you need liquidity and want to rebalance your portfolio. Full GIC vs mutual funds comparison →
For emergency funds and short-term savings, a high-interest savings account is better than either bonds or GICs.
Bond interest is taxed as regular income — the worst tax treatment of any investment income. Canadian dividends get the dividend tax credit. Capital gains are only 50% taxable. Bond interest? 100% taxable at your marginal rate.
If you hold bonds in multiple accounts, keep them in your RRSP first. The tax deferral is most valuable for the least tax-efficient asset. Hold Canadian equities and dividend stocks in your non-registered account where the dividend tax credit applies.
In a TFSA, bonds work fine too — all growth is tax-free regardless. But if you're choosing between TFSA room for bonds vs equities, equities have higher expected growth and benefit more from the tax shelter.
If you need bonds: ZAG, XBB, or VAB. Pick one, buy it, hold it. The differences between them are negligible. ZSB or XSB if you want less interest rate risk.
If you use an all-in-one ETF like VBAL (60/40) or XGRO (80/20), you already own bonds — they're built in. No need to buy a separate bond fund.
If you're under 35 with decades ahead? Skip bonds entirely. Buy XEQT, keep contributing, and ride out the dips. The math favours 100% equity over long horizons, as long as your nerves can handle it.
