A St. Lawrence County woman was critically injured in a one-car crash in Canton early Friday morning.
Sheriff's deputies say 49 year old Carolyn McDonald of Hermon was driving a 2001 Ford Windstar on County Route 27 shortly before 5 a.m.
When a deer crossed in front of her, she lost control and the minivan rolled over.
McDonald was taken to Canton-Potsdam Hospital where her condition was listed as critical.
