I'll give you one example.
This happened last January. A Quebec producer got a call from a major chain that wanted to sell one of its products, as my boss mentioned earlier. The product was subject to an agreement between the producer and the major chain. A few days later, the same chain received a better price from a Mexican producer and then decided to cancel the order from the Quebec producer.
When the major retailers come to the table, they simply say that their aim is to lower prices for consumers.
However, in this specific case, in the following days, we kept gathering information on the withdrawal of the Quebec product in favour of the Mexican product. Strangely, we saw that the price displayed on the circular and in stores hadn't dropped. The chain had simply maintained the price, even though it had obtained a product from outside Canada at a lower price.
