Competition Bureau Says Price Floors Hide Grocery Discounts
Canada's Competition Bureau says minimum advertised pricing rules set by grocery suppliers can keep the cheapest available price off the shelf tag, flyer and app.

Canada's Competition Bureau says shoppers may not be seeing the lowest price available at grocery stores because of minimum advertised pricing (MAP) policies used in the sector, which restrict how low a retailer can publicly promote a supplier's product.
Canada's Competition Bureau has put a technical piece of supplier-retailer contracting at the centre of the country's grocery affordability debate. The watchdog says shoppers may not be seeing the lowest price actually available to them at grocery stores, and it points to minimum advertised pricing policies \u2014 known in the trade as MAP \u2014 as a reason why.
The finding, reported by BNN Bloomberg, matters because it shifts attention away from the usual suspects in the food-price argument. Most of the public conversation has been about margins at the big chains and about what suppliers charge them. MAP is different: it is not a rule about what a store pays or even what it charges. It is a rule about what a store is allowed to say.
What a minimum advertised price actually restricts
A minimum advertised pricing policy is a condition a supplier attaches to selling its product. The supplier tells the retailer that if it wants to keep receiving product, promotional support, or favourable terms, it will not advertise that product below a stated floor. Crucially, the retailer is usually still free to sell below that floor. It just cannot say so in a flyer, on a shelf tag, in an app, on a website or in a digital ad.
That distinction is what makes MAP legally slippery and commercially effective at the same time. A straightforward agreement between a supplier and a retailer fixing the actual resale price is treated far more harshly under competition law in most jurisdictions. A rule about advertising sits in a greyer zone, and suppliers have leaned on it for years in categories where brand image and channel harmony matter \u2014 consumer electronics, appliances, tools, sporting goods, pet products and premium packaged food among them.
The practical effect for a shopper is simple. Price comparison in groceries happens almost entirely through advertised prices: the flyer, the loyalty app, the price-match desk. If the advertised price is held up by contract, the comparison tools consumers actually use stop reflecting the cheapest deal on offer. A discount that cannot be advertised is, for most households, a discount that does not exist.
Why the grocery aisle is a particularly sensitive place for this
Grocery is the category where Canadians notice price movement fastest and where the political temperature has been highest. It is also a category with an unusual structure: a small number of national chains buying from a small number of very large branded suppliers, with private-label products competing on the same shelf against the brands whose advertising terms are in question.
That structure amplifies whatever MAP does. If a national supplier applies the same advertised floor to every chain, the floor becomes an industry-wide feature rather than a single retailer's choice. Chains that might otherwise use a marquee branded item as a loss leader \u2014 the cereal, coffee or detergent that pulls a shopper through the door \u2014 lose that lever. Price-matching policies, which several Canadian grocers have used as a competitive weapon, also depend on a competitor's advertised price existing in the first place.
There is a second-order effect worth naming. Retailers who cannot advertise a low price on a branded good have a stronger incentive to steer promotional space toward private label, where no supplier sets the terms. That may be good for the store's margin. Whether it is good for the shopper depends entirely on whether the private-label substitute is one they actually want.
What the Bureau can do from here
The Competition Bureau's options run along a spectrum. At the softer end are market studies and guidance \u2014 publishing how MAP is being used, naming the practices it considers problematic, and giving suppliers a chance to change their contracts without litigation. That approach has the advantage of speed and the disadvantage of being unenforceable on its own.
Further along is enforcement against specific conduct. Competition law in Canada addresses attempts by a supplier to influence resale prices upward and, separately, conduct by a firm with market power that forecloses rivals. The analytical question in a MAP case is whether an advertising restriction is functionally a resale price restriction \u2014 whether, in practice, the advertised floor becomes the shelf price because no retailer can market a discount it is contractually barred from mentioning.
At the far end is a legislative fix: a statutory rule that treats advertised-price restrictions in retail food the same way the law treats resale price maintenance. That is a decision for Parliament, not the Bureau, but a Bureau finding is typically the first document a legislative change is built on.
What to watch next
At the far end is a legislative fix: a statutory rule that treats advertised-price restrictions in retail food the same way the law treats resale price maintenance.
Three signals will indicate how serious this becomes. The first is scope \u2014 whether the Bureau names categories and firms or keeps its findings general. Named conduct is far harder for a supplier to leave in place. The second is whether any grocer publicly breaks ranks. A chain that decides to advertise below a supplier's floor, and then says so, forces the question into the open quickly. The third is the response from branded manufacturers, who have historically defended MAP as protection for brand value and for smaller independent retailers who cannot match a national chain's buying power.
For investors in food retail and packaged goods, the exposure runs in both directions. Suppliers benefit from stable advertised pricing because it protects premium positioning; losing that protection could compress realised prices even without a change in list prices. Retailers gain a promotional tool but also lose an excuse, since a store that can advertise a lower price will be asked why it is not doing so.
Broader markets offered no read on the story. On Monday, 28 September 2026, the S&P 500 tracker SPY closed at $765.61, down 0.74% on the day; the Nasdaq 100 tracker QQQ finished at $736.53, down 1.07%; and the Dow tracker DIA closed at $514.02, down 0.67%. Those are US benchmarks and a Canadian grocery-pricing inquiry is not what moved them \u2014 but they frame the backdrop against which any consumer-staples repricing would land.
The immediate takeaway for shoppers is narrower and more useful than the policy debate: if the Bureau is right, the price on the tag is not always the lowest price a store is willing to accept. Asking at the counter, or checking a retailer's own clearance and manager-markdown channels, may surface discounts that the advertising rules keep off the flyer.

Frequently asked questions
What is a minimum advertised price policy?
It is a condition a supplier attaches to selling its product, setting a floor below which a retailer may not advertise that item. The retailer can often still sell below the floor at the till, but cannot promote that lower price in a flyer, shelf tag, app or online listing. It restricts speech about price rather than the price itself.
What did Canada's Competition Bureau say?
The Competition Bureau said customers might not be seeing the lowest price available at grocery stores, and attributed that to minimum advertised pricing policies used in the grocery sector. The Bureau's point is that if discounts cannot be advertised, the prices shoppers compare in flyers and apps do not reflect the cheapest deal actually on offer.
Is minimum advertised pricing illegal in Canada?
MAP occupies a grey area. Agreements that directly fix the resale price a retailer charges are treated far more severely under competition law than restrictions on how a price is advertised. The analytical question for regulators is whether an advertising floor works in practice as a resale price floor, because retailers rarely discount what they cannot publicise.
Why does MAP matter more in groceries than other retail?
Grocery price comparison runs almost entirely through advertised prices \u2014 flyers, loyalty apps and price-match desks. Chains also use marquee branded items as loss leaders to draw traffic. If a supplier's advertised floor applies across every chain, that competitive lever disappears industry-wide, and price-matching policies lose the competitor advertisement they depend on.
What enforcement action could the Bureau take?
Its options range from publishing market studies and guidance that name problematic practices, to enforcement against specific supplier conduct that influences resale prices upward or forecloses rivals. At the far end, a Bureau finding could form the evidentiary basis for Parliament to legislate a statutory rule on advertised-price restrictions in food retail.
How can shoppers find prices that are not advertised?
If advertising floors are keeping discounts off the flyer, the shelf tag is not always the store's floor price. Asking at the service counter, checking clearance and manager-markdown sections, and reviewing a retailer's own price-adjustment or price-match policy are the practical ways to surface reductions that contractual advertising limits keep out of public promotion.
