An Interac survey reports that many single Canadians spend more on groceries than people living in shared households. According to the findings, single Canadians pay about $102 per week for groceries. By comparison, couples or other shared households report paying about $80 per person per week, suggesting a per-person cost advantage when shopping is shared. The report, published on Tuesday, attributes the difference to how grocery costs are distributed among household members. The survey results reflect the pressures of higher food prices for residents who must cover grocery bills alone, while shared households split expenses across more than one person. The outlets reporting the study focus on the weekly per-person spending gap and present the figures as a direct comparison between living arrangements. The survey provides a snapshot of grocery affordability concerns for different household types, but it does not, in the provided excerpts, detail sample size, methodology, or whether the spending includes specific categories of food.
