Dominion Diving Limited is a prominent marine services and subsea contractor based in Dartmouth, Nova Scotia, operating directly out of Halifax Harbour. Established in 1969, the company has evolved from a small salvage outfit into a multi-disciplinary marine organization that supports offshore energy, scientific research, coastal construction, and port operations. It is recognized as an Indigenous-owned business and remains family-operated, maintaining a significant operational footprint in Atlantic Canada’s maritime sector.
The company’s operations are centered at its private marine terminal, known as Duck Rock, located near the narrows of Halifax Harbour. This facility serves as a 24-hour dispatch hub for its fleet and specialized crews, allowing for rapid deployment to both inshore and offshore locations. The terminal includes deep-water berths, crane capabilities, and extensive fabrication shops for welding, hydraulics, and electronics, enabling the company to maintain its equipment and modify vessels for specific project requirements without relying on external providers.
Dominion Diving’s fleet consists of multipurpose tugs, workboats, and barges designed for diverse marine tasks. These vessels, such as the *Dominion Warrior* and *Halmar*, perform duties ranging from harbour towing and barge handling to scientific research support and personnel transfers. The fleet is equipped to handle complex marine logistics, including the transport of heavy equipment to remote coastal areas and islands that lack traditional infrastructure.
A core pillar of the company’s expertise lies in commercial diving and Remotely Operated Vehicle (ROV) operations. The diving division executes a wide array of subsea tasks, including underwater welding, hull inspections, ship husbandry, and submerged infrastructure repair. Complementing this is the ROV division, which deploys observation and work-class robotic systems for deep-water inspections and interventions. These robotic assets are utilized extensively in the offshore oil and gas sector as well as the emerging marine renewable energy market.
Beyond routine maintenance and construction, Dominion Diving plays a critical role in emergency marine response. The company provides salvage services, recovery of lost assets, and environmental remediation support. Its integrated approach combines surface vessels, divers, and robotics to manage complex subsea challenges, solidifying its role as a key logistical and technical partner within Canada's eastern maritime industry.
