In September 2004, the Bureau responded to a complaint concerning a by-law of a professional association regarding advertising. The Bureau's review of the by-law identified provisions on the advertising of prices that raised concerns under the price maintenance provision of the Competition Act. The by-law stipulated that any advertisement of a price or a price reduction by a member of the association must remain in effect for a minimum period, which may have led members to believe that they no longer had control over their retail prices. The association agreed to modify the by-law so that it would no longer raise concerns under the Competition Act.
