Since 1969

Dominion Diving Limited was founded in 1969 as a small salvage based business operating out of Halifax Harbour. It has grown to be Canada’s leading Diving, ROV, and Marine Service Contractor.

The company has been heavily involved with Eastern Canada’s offshore Oil and Gas Industry since the early 1970’s while maintaining a strong presence in the inshore marine construction, ship repair/support, and scientific research industries. Our mandate is to provide 24 hour comprehensive marine service and to push the limits of innovation in the industry.


Dominion’s employment of the latest underwater technology combined with a specialized group of experienced professionals ensures the ongoing success of the projects we support. The company prides itself on its safety standards and environmental awareness. All of our projects are carried out in a safe and efficient manner with utmost concern for the environment.

The company is centrally located, in Halifax Harbour, Nova Scotia on a four acre waterfront facility. The 24 hour facility is fully equipped with a 300 foot pier, 22 ton – 80 ton cranes, a fleet of dive/tug/crew boats and a variety of flat deck barges.

A 15000 square foot office warehouse adjacent to the marine terminal houses the ROV service maintenance facility, certified welding shop and provides heated storage for all associated Diving, ROV and Marine Equipment.

Dominion Diving’s strong reputation for safe & efficient job planning and execution makes it the right choice for most any marine project or service requirement both local and abroad.
