ASI Group Ltd is a civil engineering firm based in Hamilton, Ontario, delivering underwater services that support the assessment, maintenance, rehabilitation, and construction of submerged infrastructure and environments. Founded in 1987 by a core group with backgrounds in marine biology, commercial diving, and marine construction, the company has grown to serve industries and governments worldwide. The firm maintains operations in Canada, the United States, and Chile.

Its ASI Marine division handles commercial diving, hyperbaric tunnel support, ship maintenance and repairs, and underwater remotely operated vehicle work for marine geophysical and hydrographic surveys. The company is a recognized leader in producing accurate 3D models of underwater infrastructure through sonar technology and mapping. It is also considered a leader in biofouling monitoring, control, research, and design, and runs water-treatment systems that use chemical and non-chemical approaches to minimize downtime and maintenance costs. In January 2021, ASI launched its diving program in British Columbia to support Seaspan's shipyards in North Vancouver by assisting with the docking of the S.S. Master steam tugboat.
