Gas is up 27.8% from a year ago. How to stress-test your budget before it strains your debts.

Statistics Canada reported on Oct. 19 that the price of gasoline was 27.8% higher in September than a year earlier, up from a 22.8% annual increase in August. That pushed headline inflation to 3.1%, from 3.0% the month before.¹ If you drive to work, the rise shows up in your budget before it shows up in any headline.

This is a story about arithmetic more than alarm. Prices move, and most households absorb a bump. The useful question is whether yours can, and what to do if the answer is “barely.”

What the numbers say

Gasoline drove the increase. Without it, consumer prices rose 2.2% over the year, down from 2.4% in August.¹ Other categories were calmer: food bought from stores was up 1.7%, and rent rose 2.8%. Mortgage interest cost was down 0.2%.

Statistics Canada noted that “moderating the increase in gasoline prices in September was the switch to the less expensive winter blend.”¹ In other words, the monthly figure could change again as that blend and crude prices move. The Bank of Canada has also pointed to high energy prices as a reason it is watching inflation closely.²

Why it matters for debt

Households were already carrying a steady load. In the second quarter, Canadians’ debt payments, principal plus interest, took 14.52% of disposable income, and household credit market debt equalled 176.4% of it.³ Those payments are fixed. Fuel is not, which means a price jump squeezes whatever is left after the fixed bills.

A simple illustration, not a forecast: if a household spent $200 a month on gasoline a year ago and its driving hasn’t changed, a 27.8% increase brings that to about $255.60, or roughly $667 more over twelve months. For a household with room in its budget, that is an annoyance. For one already using a credit card to cover the gap, it can be the start of a balance that doesn’t go away.

How do I stress-test my budget?

An hour is enough. This is general guidance, not advice for any one household:

1. List fixed payments. Mortgage or rent, car loan, minimum payments on every card and line of credit, insurance, phone, utilities.
2. Price your variable costs at today’s level. Use your last two months of fuel receipts or card statements, not what you spent a year ago.
3. Subtract. If what’s left is thin or negative, find out now rather than in January.
4. Test a second shock. Ask what happens if fuel rises another 10%, or your hours drop. The Financial Consumer Agency of Canada (FCAC) offers a free Budget Planner that flags categories in green, yellow or red against average Canadian spending.⁴

Can I put the extra cost on a credit card?

You can, but it adds interest on top of the original cost if you carry the balance, and it hides the gap rather than closing it. Using a card for a month or two and paying it off is different from using it every month to cover a shortfall. If the balance is growing each month, treat that as the signal.

What this means for you

If the stress test shows a shortfall, there are usually steps to take before debt becomes unmanageable: trimming flexible spending, asking lenders or the CRA about payment arrangements, and changing how much you drive where you can. If the shortfall is larger or lasting, it is worth speaking with a Licensed Insolvency Trustee, who can explain the formal options. These include a consumer proposal, which can reduce what you repay but affects your credit report for years, and bankruptcy, which has its own costs and consequences. Our consumer proposal guide explains what a proposal involves.

To see rough numbers, Harris & Partners offers a debt repayment calculator that compares options over five years, showing an approximate monthly payment and total cost for each. It’s an estimate, not a quote, and a trustee can give you figures for your own situation.
