It's the ninth annual Burgers to Beat MS day at participating A&W restaurants.
$2 from every Teen Burger sold will help those living with Multiple Sclerosis, a disease that strikes one in 340 Canadians.
Canada has the highest rate of MS in the world with an estimated 100,000 Canadians living with the disease.
A&W has raised more than $9-million in the past eight years for MS research, programs and services for those suffering from the disease.
