US snack foods group Lance is to close one of its three sugar wafer production plants in Canada.

The company, which makes products ranging from cookies to potato chips, said it will shut its site in Waterloo, Ontario.

President and CEO David Singer said Lance wants to streamline its supply chain and drive efficiency.

"We will be able to operate with fewer facilities while continuing to provide great products and service to our customers and maintaining the capacity and flexibility needed to support continued growth," Singer said.

The company will transfer its sugar wafer production to two other sites in the nearby towns of Guelph and Cambridge.

Lance will begin the process to close the Waterloo site in November.
