An emergency fund is the least exciting and most important money move you’ll ever make. It’s the reason a dead furnace or a layoff becomes an inconvenience instead of a crisis. Here’s what it is, how big it should be, and how to build one on a tight budget.
What Counts as an Emergency
Job loss, urgent car or home repairs, medical costs, emergency travel. That’s the list. A sale, a vacation, or “I deserve it” are not emergencies — raiding the fund for non-emergencies is how it never grows. Some people keep the fund in a separate account precisely so spending it takes a deliberate step.
How Much: The 3–6 Month Guideline
The standard advice is 3–6 months of essential expenses (not income — expenses). Where you land depends on your stability: single income, freelance, or commission-based? Aim for 6. Dual stable incomes with low fixed costs? 3 may be enough. Starting from zero? Even $500–$1,000 as a starter fund covers the most common surprises while you build toward the full target.
Where to Keep It: A High-Interest Savings Account
An emergency fund must be safe and accessible — not invested. A high-interest savings account (HISA) at a Canadian bank or credit union is the standard home: your money stays liquid, earns modest interest, and isn’t exposed to market swings. When comparing accounts, look at the interest rate, monthly fees, and whether the institution is a CDIC member — CDIC insures eligible deposits up to $100,000 per depositor, per member institution, per category. GICs and investments are for other goals; this money needs to be there on a Tuesday.
Building It on a Tight Budget
Automate a small amount. Even $25–$50 per paycheque, moved automatically the day you’re paid, builds quietly. You won’t miss what you never see.
Bank the windfalls. Tax refunds, bonuses, sold items — money you weren’t counting on goes straight to the fund until it’s full.
Pause, don’t cancel, other goals. Temporarily redirecting extra debt payments or investing contributions to the fund for a few months is reasonable — an emergency without a fund becomes high-interest debt, which costs far more.
The Bottom Line
You don’t need the full six months today. You need a separate account, an automatic transfer, and a rule about what counts as an emergency. Start there.
