WealthZAG vs VAB vs XBB: comparing Canadian bond ETFs
ZAG, VAB and XBB are three low-cost broad Canadian bond ETFs. They mainly hold investment-grade government and corporate bonds, but index rules, weights and duration can differ. Published MER is nearly identical; interest-rate sensitivity and composition matter more.

The real difference between these ETFs
Duration
The longer the duration, the more price generally responds to rate changes. Compare this measure with your horizon.
Credit
The mix of federal, provincial and corporate issuers influences yield and risk.
Yield to maturity
Past distribution is not the best estimate. Yield to maturity and duration better describe the current portfolio.
What each structure changes
All three seek broad investment-grade Canadian bond-market exposure. They hold many maturities and issuers, distinguishing them from a GIC or an individual bond held to maturity.
When rates rise, existing bond market values can fall; when rates decline, the reverse may occur. Distributions and reinvestment adjust gradually as bonds enter and leave the fund.
Accounts, tax and implementation
Bond interest is generally less tax-efficient than a capital gain in a taxable account. Some investors therefore evaluate placing fixed income in registered accounts, while keeping overall allocation and liquidity needs as priorities.
Overlap and concentration risk
A bond ETF has no date when your personal principal is automatically returned. It continuously renews holdings. For a fixed-date expense, a bond ladder, T-bills or GIC may have a different profile.
Diversification must be measured through underlying securities, sectors, countries, currencies and asset classes. Two different symbols can represent the same economic bet.
A neutral decision framework
Compare sensitivity
Record duration, average maturity and yield to maturity on the same date.
