How to build an emergency fund
An emergency fund is the cash you keep aside for the unexpected — a job loss, a car repair, a surprise vet bill — so that a bad week doesn't become expensive debt. It's the foundation almost every other money goal sits on. Here's how much to aim for, where to keep it, and how to get there.
How much should you save?
The common rule of thumb is three to six months of essential expenses — rent or mortgage, groceries, utilities, transportation, insurance and minimum debt payments (not your full spending).
- Lean toward three months if your income is stable and secure (e.g., a permanent salaried job with a partner's income as backup).
- Lean toward six months or more if your income is variable, commission-based, self-employed, or you're the sole earner.
If that number feels impossible, start with a starter goal of $1,000–$2,000. Even a small buffer stops most everyday surprises from going on a credit card.

Where to keep it
An emergency fund needs to be safe and quickly accessible — not invested in the market, where it could be down exactly when you need it. A high-interest savings account (HISA) at a CDIC-member bank is the standard home: your money earns interest, stays liquid, and is protected within CDIC limits.
Keep it separate from your everyday chequing account so you're not tempted to spend it, but not so hard to reach that you can't get it within a day or two.
A realistic plan to build it
Automate a fixed transfer to your savings account the day after each payday — treat it like a bill. Even $25–$100 per paycheque compounds into a real buffer over a year.
Redirect one-off windfalls (a tax refund, a bonus, a GST/HST credit) straight into the fund to accelerate it.
Once it's full, stop and redirect that same automatic transfer toward your next goal — paying down debt or investing in a TFSA or RRSP.
Frequently asked
Should I pay off debt or build an emergency fund first?
Do a little of both: build a small starter buffer ($1,000–$2,000) so surprises don't create new debt, then focus on high-interest debt (like credit cards) before finishing the full fund.
Is a TFSA a good place for an emergency fund?
It can be — a TFSA holding a high-interest savings product keeps the money liquid and any interest tax-free. Just keep it in cash/HISA form, not invested in volatile assets, and remember TFSA withdrawal room comes back only the following calendar year.
