The Canada Atlantic Railway Company (CAR) was a historic North American railway located in Ontario, southwestern Quebec and northern Vermont. It connected Georgian Bay on Lake Huron with the northern end of Lake Champlain via Ottawa, ON. It was formed in 1897 through a merger of three separate railway companies that John Rudolphus Booth had either purchased or created, beginning in 1879. The CAR was owned by Booth for eight years after its formation until he sold it to the Grand Trunk Railway (GTR) in 1904.
