Bid rigging is considered a form of price fixing and is illegal in both the United States (s.1 Sherman Act) and Canada (s.47 Competition Act). In the United States, agreements to fix, raise, lower, stabilize, or otherwise set a price are illegal per se.[11] It does not matter if the price agreed upon is reasonable or for a good or altruistic cause or the agreement is unspoken and tacit. In the United States, price-fixing also includes agreements to hold prices the same, discount prices (even if based on financial need or income), set credit terms, agree on a price schedule or scale, adopt a common formula to figure prices, ban price advertising, or agree to adhere to prices that are announced.[12]
