A third individual, a twenty-year-old man, is facing criminal charges.
The incident involved two vehicles near Saint-Rémi in Quebec's Montérégie Wednesday afternoon.
Police said one driver lost control and his car bounced off a culvert before slamming into a hydro pole.
A 15-year-old girl was thrown from the vehicle and died at the scene.
The 19-year-old driver was rushed to a hospital where he died a few hours later.
Quebec Police Sgt. Claude Denis says police arrested the driver of the second car. He is scheduled to appear in Longueuil court today.
