RCMP say that 17-year-old Dalin Torresan and his 14-year-old brother, Logan, collided with a pickup truck on Monday afternoon.
Mounties say the teens were pronounced dead at the scene.
The driver of the pickup, a 54-year-old man, was taken to hospital with non-life threatening injuries.
RCMP say it appears the car was approaching the highway from a side road and failed to proceed safely after stopping at a stop sign.
No charges are pending.
