OTTAWA, June 9 (Reuters) - Canada's Competition Bureau said on Monday it was suing DoorDash and its Canadian subsidiary for allegedly advertising misleading prices and discounts.

The bureau said in a statement that it found that consumers were unable to purchase food and other items at the advertised price on DoorDash's websites and mobile applications due to the addition of mandatory fees at checkout.

The bureau said it was suing to stop DoorDash from what it called deceptive price and discount advertising. It is seeking a penalty from the companies and wants them to offer restitution to affected consumers.
