Canadian Tire, Mr. Gas and Pioneer Energy have been fined just more than $2 million for fixing the price of gasoline in Kingston, Ont., and nearby Brockville in 2007.

In a news release, the Competition Bureau said it uncovered evidence the three competitors agreed among themselves to set the price of gas at the pump between May and November that year.

The bureau said the "gas retailers or their representatives in these local markets phoned each other and agreed on the price they would charge customers for gasoline."

All three companies pleaded guilty to price-fixing under the Competition Act in Brockville Superior Court.
