Police have identified three young women from Ontario, Quebec and Nova Scotia killed in a weekend car crash in Alberta.

The victims were Katie Elizabeth Maddock, 22, of Kentville, N.S.; Chelsil Robinson, 20, from Hamilton, Ontario; and Audrey Vezina, 26, from Temiscaming, Quebec.

All three worked at the Fairmount Chateau Lake Louise in Alberta.

Their car collided with a family of four from Ontario. The family survived with broken bones.

Police say they don't expect to lay any charges in connection with the collision.

The crash was the third fatal pile up on the single lane stretch of Trans-Canada Highway in several weeks. People living in the area say the highway should be twinned.
