OTTAWA (Reuters) -Canada's Competition Bureau said on Monday it was suing DoorDash ( DASH ) 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 ( DASH ) websites and mobile applications due to the addition of mandatory fees at checkout.

The bureau said it was suing to stop DoorDash ( DASH ) 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.
