Your grocery flyer may not tell the whole price story. On September 28, 2026, Canada’s Competition Bureau announced an investigation into minimum advertised pricing policies in the grocery sector. These rules can prevent a retailer from promoting a price below a supplier’s advertising floor, even when the store may be willing to charge less. That matters if you use flyers or shopping apps to decide where to spend your grocery budget. The announcement is a new investigation, not a finding that a particular grocer or supplier has broken the law. It also does not identify a guaranteed hidden discount at your local store. The useful takeaway is narrower: advertised prices can be an incomplete guide to the choices available, so treat them as a starting point rather than a complete price list.
Understand the advertising floor. A minimum advertised pricing policy sets the lowest price at which a retailer may advertise a supplier’s product. The bureau says restrictions can cover flyers, websites, apps, social media and other advertising. Suppliers can impose the policies directly, or suppliers and retailers can negotiate them. Importantly, an advertising restriction is not necessarily the same as a minimum checkout price: a store may still be allowed to sell for less. That distinction helps explain why investigators are interested in what shoppers can see before choosing a store. It does not mean every difference between an online listing and a shelf label comes from such a policy. Location, timing, membership conditions and the shopping channel all need checking before you compare two offers or draw conclusions about their cause.
The concern goes beyond missing a special. The bureau says some retailers may decide an in-store discount is not worth offering if they cannot advertise it to attract customers. Its information notice also asks whether stores might stop carrying certain products because of these rules. Investigators are examining possible effects on price competition and the ability of discount grocers to compete. These are questions being investigated, not established outcomes for every product. The Canadian Press, in a September 28 report published by iPolitics, quoted University of Guelph professor Mike von Massow explaining that suppliers can put minimum advertised prices in sales contracts. He also noted that a grocer might promote a competing product instead. For shoppers, that makes checking alternatives more useful than assuming a familiar brand’s advertised price is the only relevant option.
Keep using flyers, but add a quick shelf check. Throwing away a useful comparison tool would be the wrong response to this announcement. Before your normal shop, use advertised offers to shortlist the stores and products that fit your meal plan. Once there, compare those offers with shelf prices for equivalent products, including store brands and other brands you would actually use. Check the same package size or a comparable unit price rather than the biggest sale sign. If you see a lower shelf price than expected, confirm which product and conditions it covers. There is no reason to buy extra just because the deal was not in the flyer. A bargain only helps the household budget when it replaces something needed and can be used before it goes to waste.
Avoid turning uncertainty into extra driving. The investigation does not provide a list of stores with unadvertised bargains, so it is not a reason to make speculative trips across town. Compare what you can verify, and build any additional checks into errands you already need to make. If a retailer offers price matching, read its current terms before assuming an in-store price elsewhere will qualify; the bureau’s announcement does not change an individual store’s policy. For online orders, judge the total payable, including applicable service or delivery charges, rather than one attractive item price. Consider keeping a small record of regular purchases with their package sizes, dates and store locations. Over time, your own receipts can make an advertised promotion easier to assess without requiring a complicated shopping spreadsheet.
Separate evidence from suspicion. Similar advertised prices across stores are not, by themselves, proof of an unlawful agreement or a minimum advertised pricing policy. The bureau’s information page says that, depending on the circumstances, these policies may be examined under Competition Act provisions dealing with price maintenance, abuse of dominance or agreements that harm competition. It also discusses possible benefits, including encouraging retailers to carry and promote products from newer or less established suppliers. That is why the details matter. Shoppers do not need to decide the legal question to make a better purchase. Focus on the observable facts: what product was offered, where, when, at what price and under which conditions. Keep those facts separate from any explanation you cannot verify, especially when posting about a store online.
Watch the investigation, not promises of instant savings. The bureau is inviting individuals, retailers, suppliers, distributors and manufacturers with relevant information to share their experiences through its official information page. Someone with direct knowledge of a pricing restriction can describe how it was communicated and whether it affected promotions or buying decisions. An ordinary price complaint is not necessarily evidence of such a restriction, and consumers should not expect this announcement alone to produce an immediate refund or price reduction. For this week’s grocery run, the practical response is simple: use flyers to plan, compare acceptable alternatives at the shelf, and judge the full basket before switching stores. Better information can support better shopping decisions today, while the investigation works through questions that a sale tag cannot answer.
