Manitoba has put a fresh grocery-shopping idea back in the national conversation: make prices easier to compare at the shelf. On June 22, the province released its Manitoba Grocery Price Study and said it plans to adopt unit pricing as part of a broader package aimed at lowering food costs. Unit pricing means showing the price per common measure, such as per 100 grams, per kilogram, per litre or per roll, beside the regular shelf price. For shoppers, the useful part is simple: it can reveal when the bigger box is not actually the better deal, when a sale tag is only average, or when a package has quietly shrunk while the sticker price stayed familiar.
The timing matters because grocery inflation is still running hotter than the overall basket. Statistics Canada’s May Consumer Price Index showed the headline CPI up 3.2% from a year earlier, while food purchased from stores rose 4.3%. Fresh vegetables were up 9.0% year over year, and tomato prices jumped 45.2%, with StatCan pointing to tighter Mexican supply linked to poor weather, reduced planted acreage and U.S. tariffs. Those are exactly the kinds of swings that make price-per-unit comparisons helpful. When tomatoes are expensive, comparing canned tomatoes by 100 millilitres, cherry tomatoes by 100 grams and larger field tomatoes by kilogram can turn a vague “that seems pricey” feeling into a clear decision.
Manitoba’s study frames unit pricing as a consumer-protection tool, not a magic price cut. The province’s release says the study also recommends reintroducing Nutritious Food Basket costing, funding Harvest Manitoba’s Food Transformation Centre, and looking at a new grocery store in downtown Winnipeg to improve access. It also connects grocery costs to competition issues, including property controls that can limit where rival stores open. That echoes the Competition Bureau’s 2023 grocery market study, which argued Canada needs more grocery competition and noted that most Canadians buy food from stores owned by a handful of major chains. For everyday shoppers, the takeaway is to watch both the shelf label and the local market: the best flyer is less useful if there are only one or two realistic stores nearby.
Even outside Manitoba, shoppers can use a unit-pricing routine right now. Pick one measure for each aisle and stick with it: cereal and snacks by 100 grams, oils and drinks by litre, toilet paper by sheet or roll, detergent by load, meat by kilogram, and produce by kilogram unless the store prices each item. Then compare the house brand, the national brand, the “family size” package and the sale item using that measure. If the shelf does not show unit pricing, use your phone calculator: divide the price by the number of grams, millilitres, sheets or loads, then scale it to a number you can understand. A $4.99 650-gram jar is about 77 cents per 100 grams; a $6.49 1-kilogram jar is about 65 cents per 100 grams. The second jar is cheaper only if your household will use it before it spoils.
The shrinkflation check is just as important. Keep a short note in your phone for five repeat buys: coffee, cereal, yogurt, crackers and laundry detergent are good candidates because package sizes change often. Record the size, not just the price. If your usual granola drops from 475 grams to 425 grams, the shelf price can look stable while the unit price rises. This is also where “buy two” offers deserve a pause. A two-for deal is not a deal if the unit price is higher than the store brand beside it, if the product will expire before you finish it, or if it pushes you to buy a snack you would normally skip. The goal is not to turn every shop into homework; it is to protect the repeat purchases that quietly decide the monthly bill.
For CanadianShopping.com readers, the practical move this week is to build a small “unit price basket” before the next grocery run. Choose 10 household staples, write down the size you usually buy, and check the price per unit at two stores or one store plus one online cart. Pay special attention to produce, coffee, bread, dairy alternatives, cleaning products and paper goods, because they can hide big differences behind similar shelf prices. Manitoba’s plan may put clearer labels in front of shoppers there, but the habit travels. Until unit pricing is consistent everywhere, the best defence against shrinkflation is a short list, one calculator check, and a willingness to switch package sizes when the math changes.
