Canada has abundant oil, gas, hydroelectric and mineral resources. Yet another vast energy resource remains largely untapped: the powerful winds that sweep across the country’s Atlantic, Pacific and Arctic coastlines. Increasingly, attention is turning towards floating offshore wind turbines, a technology that could allow Canada to harness deep-water wind resources that were previously beyond reach.

While Europe has become the global leader in offshore wind deployment, Canada is only beginning to develop the regulatory frameworks and infrastructure needed to support a domestic offshore wind industry. Nevertheless, industry analysts, researchers and policymakers believe floating offshore wind could play a significant role in helping Canada achieve its climate targets while creating a new clean-energy economy.

Traditional offshore wind turbines are mounted on fixed foundations driven into the seabed. This approach works well in relatively shallow water but becomes economically and technically challenging once depths exceed around 60 metres. Floating offshore wind turbines solve this problem by placing wind turbines on buoyant platforms anchored to the seabed with mooring systems. This allows turbines to operate in much deeper waters, opening access to stronger and more consistent wind resources.

According to Natural Resources Canada’s offshore wind programme, offshore wind generally benefits from higher and more reliable wind speeds than equivalent onshore installations. The federal department notes that Canada’s extensive coastline places the country in a favourable position to participate in a rapidly expanding global offshore wind sector. For Canada, floating technology is particularly important because many of the nation’s highest-quality offshore wind resources occur in deep waters where conventional fixed-bottom turbines are impractical.

While offshore wind projects could eventually emerge across Canada, Atlantic Canada has become the focal point for early development efforts. The region possesses some of North America’s strongest offshore wind resources. A recent assessment highlighted average offshore wind speeds exceeding 9 to 11 metres per second in many locations, creating highly favourable conditions for electricity generation.

Research by Net Zero Atlantic and Stantec has identified substantial offshore wind potential across Nova Scotia, Newfoundland and Labrador, New Brunswick and Prince Edward Island. The studies concluded that deeper offshore waters, particularly around Newfoundland and Labrador, are especially suited to floating wind technologies.  Further analysis published by REGlobal indicates that Atlantic Canada retains tens of gigawatts of feasible offshore wind capacity even after environmental, technical and economic constraints are considered. Nova Scotia has emerged as a particularly ambitious province. Natural Resources Canada reports that Nova Scotia has established a target to offer leases for up to five gigawatts of offshore wind development by 2030.  In February 2026, Nova Scotia and the state of Massachusetts announced plans to explore opportunities for exporting clean energy generated from offshore wind resources, highlighting growing international interest in Atlantic Canada’s wind potential.

As outlined in a recent technical review, Floating Offshore Wind Farms in Canada, floating offshore wind technology offers several advantages beyond simply accessing deeper water. The first is energy production. Winds further from shore tend to be stronger and less turbulent, improving turbine efficiency and increasing electricity generation. A second benefit is reduced visual impact. Because floating turbines can be positioned much further from the coastline than fixed-bottom installations, they are less visible from land.

There are also environmental considerations. Floating platforms generally require less disturbance of the seabed during installation compared with conventional offshore wind foundations. Some researchers have suggested that the resulting structures may provide habitats that support marine biodiversity, although impacts remain site-specific and require careful assessment.

Importantly for Canada, floating offshore wind could help support communities affected by the gradual transition away from fossil fuel industries. Many of the engineering, fabrication, marine operations and project-management skills developed in the offshore oil and gas sector are directly transferable to offshore renewable energy developments.

Despite the enthusiasm, Canada faces a number of obstacles before floating offshore wind becomes a major contributor to the national electricity mix. The most obvious challenge is cost. Floating offshore wind remains more expensive than conventional onshore wind and, in many cases, more costly than fixed-bottom offshore wind. Development requires specialised ports, heavy-lift vessels, subsea electrical infrastructure and advanced manufacturing capabilities. Canada must either build these capabilities domestically or rely on international supply chains that are already under increasing pressure from growing global demand.

Environmental and operational conditions present additional complications. Offshore projects in Atlantic Canada may encounter severe storms, harsh winter conditions and, in some regions, sea ice. These factors create engineering challenges that differ from many established European offshore wind markets.  Another significant hurdle involves the transmission of electricity from offshore installations to users on land. Even where wind resources are excellent, the costs of connecting projects to existing electricity networks can be substantial. Analysts have also highlighted interactions with fisheries, shipping routes, marine protected areas and seabed conditions as factors that will influence project siting and development.

Although Canada currently has no operational floating offshore wind farms, several proposed developments are moving through planning and regulatory processes. Among the projects attracting attention is Nova East Wind in Nova Scotia, which has been identified as a potential early floating offshore wind development. Industry observers view such projects as important test cases that could demonstrate the commercial viability of deep-water offshore wind in Canadian conditions.  The success of these initial developments will likely determine whether larger-scale deployment follows.

Canada’s interest in floating wind is part of a broader international trend. Countries including the United Kingdom, Norway, Portugal and Japan have already launched commercial-scale floating offshore wind projects. China is also investing heavily in offshore wind development, both fixed-bottom and floating. As the technology matures, costs are expected to fall. Industry analysts anticipate that economies of scale, improved manufacturing techniques and larger turbine designs will make floating offshore wind increasingly competitive over the coming decade. Natural Resources Canada notes that offshore wind globally added 8 gigawatts of new installations in 2024 and that investment in offshore wind technologies is expected to continue expanding rapidly.

Floating offshore wind is unlikely to replace other renewable energy sources in Canada. Hydroelectric power will remain dominant for many provinces, while solar, onshore wind and emerging energy-storage technologies will all play important roles.
