Best Canadian Bond ETFs in 2026
Comparing ZAG, VAB, XBB, and the strategic choice between short-term and aggregate bonds.
The Role of Bonds in a Portfolio
While equities drive long-term growth, bonds are the anchor of your portfolio. They provide regular income and, more importantly, act as a shock absorber during stock market crashes. By holding a Canadian bond ETF, you ensure you have capital available to rebalance when equities go on sale.
Best Aggregate Bond ETFs
Aggregate bond ETFs track the broad Canadian bond market, holding a mix of federal, provincial, and high-quality corporate bonds across various maturities (short, medium, and long-term).
1. ZAG - BMO Aggregate Bond Index ETF
ZAG is one of the most popular bond ETFs in Canada. It offers excellent liquidity, low fees, and a yield that accurately reflects the current interest rate environment.
- MER: ~0.09%
- Holdings: ~1,500 bonds (approx. 70% government, 30% corporate)
- Best for: A one-ticket, core fixed-income holding for any portfolio.
2. VAB - Vanguard Canadian Aggregate Bond Index ETF
VAB is Vanguard's answer to the core bond allocation. It operates very similarly to ZAG, offering broad exposure to investment-grade Canadian bonds.
- MER: ~0.09%
- Holdings: ~1,100 bonds
- Best for: Investors who prefer Vanguard products or are building a suite of Vanguard ETFs.
3. XBB - iShares Core Canadian Universe Bond Index ETF
XBB is the oldest of the big three aggregate bond ETFs. While its MER was historically higher, BlackRock has lowered it to remain competitive with ZAG and VAB.
- MER: ~0.10%
- Holdings: ~1,600 bonds
- Best for: A highly established, broad-market bond holding.
Short-Term vs. Aggregate Bonds
One of the most common questions is whether to buy an aggregate bond fund or a short-term bond fund (like VSB or XSB).
Duration Risk: Aggregate bond funds typically have a duration of around 7-8 years. This means if interest rates rise by 1%, the ETF's price will drop by roughly 7-8%. Short-term bond funds have a duration closer to 2-3 years, meaning they are much less sensitive to interest rate hikes.
Yield: In a normal yield curve environment, aggregate bonds pay a higher yield than short-term bonds to compensate for the higher duration risk.
The Verdict: If you are terrified of interest rates rising, short-term bonds are safer. However, for a long-term, balanced portfolio, an aggregate bond ETF provides better diversification and income.
