Buying groceries for one can look modest at the checkout, yet the weekly math tells a harsher story. Canadians who live alone report spending about $102 a week on groceries, compared with $80 per person in shared households. That $22 gap works out to roughly $1,144 over a full year—money that could otherwise cover utility bills, transit, medication or emergency savings.
The pressure matters because solo living is no longer unusual. One-person households are Canada’s largest household category, and millions of adults now absorb food costs without a second income, a second appetite or someone to help finish the family-sized package. The result is a grocery system in which independence can carry a quiet but persistent premium.
The $22 Gap Adds Up Quickly
The $22 figure comes from findings commissioned by Interac and collected from 1,500 Canadian adults between May 8 and May 12, 2026. Respondents were drawn from Léger’s online panel, and the results were weighted by age, gender and region to reflect the national population. Interac reported a margin of error of plus or minus 2.5 percentage points, 19 times out of 20. Nearly six in 10 solo residents said they believe they pay disproportionately more per person, while 77 per cent said their grocery bills keep rising regardless of what they do.
Those numbers should be read as self-reported household spending, not as a transaction-by-transaction audit of every grocery receipt in Canada. Even so, the pattern is economically plausible and nationally significant. Statistics Canada counted 4.4 million people living alone in 2021, more than double the 1.7 million recorded in 1981. One-person households represented 29.3 per cent of all households, making them the country’s most common household type. A weekly disadvantage that looks small on paper therefore touches a large and growing part of the population.
Bulk Discounts Favour Bigger Households
The grocery aisle often rewards volume. A larger bag of rice, family pack of chicken or multi-pack of yogurt usually lowers the price per unit, but only when the household can use the product before it spoils. A couple can divide a 12-pack of eggs, a large loaf or a two-kilogram bag of produce across twice as many meals. A solo shopper must either eat the same foods repeatedly, create freezer space, share the purchase or accept that the cheaper unit price may not become a real saving.
Economists describe this broader advantage as a household economy of scale: needs rise as more people join a household, but not in a perfectly one-for-one fashion. Statistics Canada incorporates that principle when adjusting income measures for household size. Canadian food-waste research has also identified large retail package sizes as a particular challenge for single-person households trying to consume food before it spoils. In practical terms, the sticker price can be misleading. The largest package may be the cheapest per gram while still being the most expensive choice once unused portions are counted.
Spoilage Turns Value Packs Into False Savings
Spoilage is where the solo-shopping premium becomes especially visible. Interac found that 32 per cent of Canadians living alone say food often goes to waste before they can use it. For someone buying fresh herbs, salad greens, bread and dairy for one, the problem is rarely a lack of intention. It is a race against shelf life. A value-sized container can appear economical on Saturday and become an expensive compost-bin contribution by Thursday.
The national scale of household food waste shows why that matters. Love Food Hate Waste Canada says 63 per cent of food discarded by Canadian households could have been eaten. Its updated estimate puts avoidable waste at about 140 kilograms and more than $1,300 per average household each year. Vegetables account for 30 per cent of wasted food by weight, followed by fruit at 15 per cent, leftovers at 13 per cent, bread and bakery products at 9 per cent, and dairy and eggs at 7 per cent. Solo households are not responsible for all of that waste, but fewer mouths and oversized packages can make the problem harder to avoid.
Inflation Magnifies the Solo-Household Premium
The $22 difference is landing during an unusually punishing period for food budgets. Statistics Canada reported that grocery prices were 3.8 per cent higher in April 2026 than a year earlier, while the overall Consumer Price Index rose 2.8 per cent. The pressure has compounded over several years: food purchased from stores rose 9.8 per cent in 2022, 7.8 per cent in 2023 and 2.2 per cent in 2024. Grocery prices then increased another 3.5 per cent on an annual-average basis in 2025.
For a shared household, a price increase can sometimes be spread across two paycheques and larger-volume purchases. A person living alone faces the full increase while also paying the entire rent, internet bill, hydro charge and household insurance premium. That helps explain why 77 per cent of solo respondents said their grocery bill keeps climbing regardless of their efforts. Switching brands or chasing flyers may slow the increase, but it cannot fully remove the structural disadvantage of purchasing perishable food for one. Inflation does not create the solo premium by itself; it makes every weakness in the model more expensive.
Food Insecurity Risk Is Not Distributed Evenly
Higher grocery spending does not automatically mean every person living alone is food insecure. Income, age, savings, housing costs and access to transportation all shape whether someone can reliably afford enough food. Still, the latest national income data show that unattached working-age Canadians face elevated risk. In 2024, 30.4 per cent of unattached non-seniors lived in households experiencing some level of food insecurity, compared with 24 per cent of Canadians overall. The rate was lower for unattached seniors, at 13 per cent, though still higher than the 9.9 per cent recorded among people in senior families.
The distinction matters because “living alone” includes very different realities: a well-paid professional in a downtown condo, a newly separated parent, a student starting a first job, or an older adult managing a fixed income. The same $22 gap can be irritating for one person and destabilizing for another. For someone with little room in the budget, an extra $1,144 a year may mean reducing meat purchases, postponing other necessities, relying on food programs or skipping social activities. The grocery premium is therefore best understood as an affordability multiplier, not a complete explanation of hardship.
Canadians Are Redesigning Their Grocery Carts
Canadians are responding by changing what they put in the cart. Interac found that 48 per cent had reduced or stopped buying premium cuts of meat, while prepared meals and premium deli products were also losing ground. Another 38 per cent had shifted toward store or no-name brands during the previous six months. These adjustments show shoppers moving beyond occasional coupon use and redesigning everyday habits around lower-cost proteins, simpler meals and private-label products.
Yet the findings also reveal limits to austerity. Half of respondents still bought snacks such as chips and chocolate as a personal treat, and 23 per cent continued to purchase artisanal bread or pastries. Those choices are easy to dismiss as unnecessary, but small pleasures can carry emotional value when larger expenses feel uncontrollable. A solo shopper may skip a steak, choose generic pasta sauce and still keep a favourite chocolate bar in the basket. That is not necessarily careless spending; it is often a negotiated compromise between financial discipline and quality of life. The modern grocery cart has become a record of what households are willing to surrender—and what they are determined to preserve.
Sharing the Bill Can Create Different Pressures
Sharing a household lowers the average grocery cost, but it does not eliminate tension. Nearly half of partnered Canadians in the Interac findings said they approach grocery spending differently from their partner, and 28 per cent said grocery costs had strained their relationship during the previous six months. Four in 10 identified a familiar conflict: one person follows the list while the other makes impulse purchases. Disagreements also emerged over which items count as necessities and whether name brands are worth the extra money.
Age and location shaped the experience. Grocery spending was a source of relationship tension for 39 per cent of millennials, compared with 17 per cent of boomers. In British Columbia, only 58 per cent of people in shared households said they managed the grocery budget well together, versus 73 per cent in Quebec. Solo shoppers escape those negotiations, and 70 per cent of people who previously lived with a romantic partner said they were relieved to make grocery decisions without compromise. Living alone may cost more, but for many, the freedom to choose every item remains a meaningful benefit.
Better Packaging and Price Information Could Help
Some of the pressure can be reduced through better information and food management, although personal discipline cannot solve a market built around larger households. Canada’s Competition Bureau has argued that standardized unit pricing would make it easier to compare differently sized packages. Unit prices are already displayed by many retailers, but Quebec is the only province where they are legally required. Clearer national standards would help solo shoppers see when a smaller package is genuinely cheaper after waste risk is considered.
At home, federal guidance recommends planning meals, checking the refrigerator before shopping, buying only what can be used and freezing foods that may spoil. Canada’s Food Guide also promotes batch cooking and freezing meal-sized portions, while agricultural guidance suggests keeping canned, frozen and dried foods available because they last longer. These tactics can turn a family-sized soup, curry or pasta sauce into several convenient meals. Retailers could also respond with more single-portion produce, flexible multi-buy offers and resealable packaging. The larger lesson is that living alone should not require choosing between paying more per gram and throwing food away.
