Toronto police have laid numerous charges against a 21-year-old man accused of drinking and driving in a high-speed crash that killed three women and left two people in critical condition.

Police allege that Roman Luskin's BMW was travelling at about 200 kilometres per hour on Saturday night when it smashed into a Honda Odyssey van near Tobermory Drive and Finch Avenue. The force of the collision split the van in half.

Hon To, 44, her daughter Christine Taing and a third passenger were thrown from the van, and officials pronounced them dead at the scene.

To's husband, Pho Taing, and another passenger are in a Toronto hospital with serious injuries.

Luskin faces 16 charges, including criminal negligence causing death and bodily harm, impaired driving causing death and bodily harm and refusing to provide a breath sample.

Police said they've investigated Luskin for drinking and driving in the past.

They are also considering laying numerous additional driving charges. He appeared in court at Old City Hall on Monday, but his hearing was postponed until Tuesday to give the court time to find a Russian interpreter.
