Breton Industrial & Marine
Point Tupper NS
The Strait of Canso Marine Railway Co., just Canso Marine Railway Co., was a repair yard that was in operation at least as early as 1866. It was acquired by Murray Osborne in 1970 and renamed Breton Industrial & Marine Ltd. Osborne added a dry-dock and the fabrication capacity required to build ships and operated the yard until at least 1988. It is now occupied by McNally International, the marine construction company that was purchased by Weeks Marine in 2011.
