Canada has the world's longest coastline, the second-largest exclusive economic zone, and a seafood sector that is among the most export-intensive industries in the country. The ocean economy is both an economic story and an Indigenous rights story, and the two cannot be told separately.
Canada has the world's longest coastline, the second-largest exclusive economic zone (EEZ) after the United States, and commercial fisheries across three oceans. The seafood sector generates approximately $7 billion in landed value annually and supports over 70,000 direct jobs in harvesting and processing, concentrated in some of Canada's most economically vulnerable coastal and Indigenous communities. It is one of the most export-intensive industries in Canada, with roughly 85% of production going to international markets, predominantly the US, EU, China, and Japan.1 And it is almost entirely absent from national trade intelligence coverage.
The ocean economy is not simply a fisheries story, though fisheries anchor it. Ocean technology and innovation, much of it emerging from Dalhousie University, Memorial University of Newfoundland, and the Ocean Frontier Institute, represents one of Canada's most credible positions in the global marine science and technology sector. Ocean energy, encompassing tidal power, offshore wind, and wave energy, is most advanced in Nova Scotia, where the Bay of Fundy's extraordinary tidal range has made Canada a world reference point for tidal energy development. Aquaculture, particularly salmon in BC and bivalves in Atlantic Canada, is the fastest-growing component of Canadian seafood production. Arctic shipping, as northern sea routes become commercially viable with climate change, creates both opportunity and sovereignty complexity that is inseparable from the defence and Indigenous dimensions of Canada Forward.
The ocean economy is also a climate change story in a way that few other sectors are. A Simon Fraser University study projects that some parts of Canada could see a 50% drop in marine resources under high-emissions scenarios, with Arctic communities and Indigenous peoples identified as the most vulnerable to these shifts.2 The same climate change that is opening Arctic shipping routes and creating new fishery opportunities in northern waters is threatening established Pacific and Atlantic fisheries through warming temperatures, acidification, and shifting stock distributions. The communities most dependent on what the ocean produces are often the least equipped to absorb rapid ecological change.
The most important structural fact about Canada's ocean economy is one that mainstream trade analysis consistently fails to address: it is not possible to discuss Canadian fisheries honestly without discussing Indigenous treaty rights, because those rights are constitutionally protected, commercially significant, and actively contested in courts, on the water, and in DFO policy processes. The Supreme Court of Canada's 1999 Marshall decisions affirmed the treaty right of Mi'kmaq, Wolastoqey, and Peskotomuhkati peoples to fish in pursuit of a moderate livelihood. More than 25 years later, the full implementation of that right remains incomplete, contentious, and the subject of ongoing federal investment, nation-to-nation negotiation, and academic research. Any intelligence platform that covers Canadian fisheries and seafood trade without addressing this is covering only part of the story.
This section addresses constitutionally protected Indigenous treaty rights in Canadian fisheries. CTI is committed to covering this dimension honestly, not as a regulatory footnote but as a central economic and governance story. We welcome engagement from Indigenous communities, researchers, and organizations working in this space. If you have research, perspectives, or corrections to offer, please reach out through our contact page.
The Supreme Court of Canada's 1999 decisions in R. v. Marshall affirmed that Mi'kmaq, Wolastoqey, and Peskotomuhkati peoples hold constitutionally protected treaty rights to harvest and trade fish in support of a moderate livelihood. These rights are not subordinate to federal fisheries management preferences. They predate Confederation. They are protected under Section 35 of the Constitution Act, 1982. And 25 years after the Supreme Court's ruling, their full implementation remains one of the most consequential unresolved governance questions in Atlantic Canada's economic life.4
The federal government committed $66.3 million in the 2024-25 Supplementary Estimates to continue implementing moderate livelihood fishing rights for 34 Mi'kmaq and Wolastoqey communities and the Peskotomuhkati Nation at Skutik, plus $60.1 million to advance reconciliation on Indigenous rights and fisheries issues more broadly.6 These are not trivial sums, but they are invested in a process that has been described by researchers as fundamentally constrained by the structure of federal fisheries management itself. Bailey and Paul's 2024 paper in Frontiers in Marine Science, comparing Mi'kmaq fishery development to Maori fisheries in New Zealand following their 1992 settlement, finds that the primary barriers to Indigenous self-determination in fisheries are not a lack of harvest rights but a lack of access to market infrastructure, processing capacity, and governance authority that harvest rights alone cannot provide.4
This distinction matters for anyone analyzing the economic potential of Atlantic Canada's seafood sector. The Marshall communities' growing participation in the lobster, snow crab, and other commercial fisheries represents both a rights implementation story and a commercial development story. DFO's Atlantic Integrated Commercial Fisheries Initiative has supported communities in acquiring commercial fishing licences, vessels, and gear. Over $191 million in annual landings now flow through Marshall communities. But vertical integration, the ability to own and operate processing facilities and sell directly to international markets rather than selling catch to non-Indigenous processors, remains constrained by provincial regulations and capital access gaps that federal fisheries policy cannot address alone.
Beyond the Atlantic, the ocean economy's Indigenous dimension extends to Inuit fisheries and governance in Nunavut, where DFO and the Qikiqtani Inuit Association signed the Qikiqtani Fisheries Agreement and are co-developing the Nunavut Fishery Regulations to advance Inuit self-determination.7 In BC, the transition away from open net-pen salmon aquaculture involves deep consultation with First Nations whose food security, cultural practices, and economic interests are directly implicated. The Haida Gwaii Pacific herring rebuilding plan, cited by Oceana Canada as an example of successfully pairing Indigenous Knowledge Systems with Western fisheries science, demonstrates what co-governance can produce when it is structured around genuine partnership rather than consultation.
Canadian seafood is overwhelmingly destined for international markets. Lobster, snow crab, shrimp, salmon, and groundfish are the dominant export categories. The US is the largest market, followed by China and Japan, with growing EU access through CETA. The sector's export intensity, approximately 85% of production leaving Canada, reflects both genuine international demand and a domestic processing gap that could capture more value at home.
Atlantic lobster is Canada's single most valuable seafood export. Nova Scotia, New Brunswick, PEI, and Newfoundland collectively produce the majority of North Atlantic lobster landings, and Canadian lobster has established premium positioning in US, EU, and Asian markets. Snow crab, also concentrated in Atlantic Canada, is the second major export. Both fisheries have seen significant licence value appreciation over the past decade, creating wealth concentrated among licence holders, which intersects with the Marshall rights question about how that wealth is distributed across fishing communities.
The value-added gap in Canadian seafood is structural and mirrors the critical minerals story. Canada exports whole or minimally processed lobster and crab to markets where further processing, portioning, packaging, and retail preparation add significant margin. Processing capacity that could exist in Yarmouth or St. John's exists instead in Boston and Boston's hinterland. The reasons are a combination of labour costs, regulatory environment, infrastructure investment, and the historical development of processing relationships, but the economic consequence is that Canadian fishing communities capture the extraction value and export the transformation value.
CETA provides relevant context. The Canada-EU Comprehensive Economic and Trade Agreement includes specific provisions for fish and seafood products, with tariff reductions on processed seafood entering the EU that are more favourable than unprocessed product in some categories. This creates an explicit policy incentive to add value in Canada before export to EU markets, but uptake among Canadian processors has been limited by the capital and logistical challenges of shifting established export patterns. CTI tracks CETA seafood provisions in the Agri-food weekly report.
The Ocean Frontier Institute, a partnership between Dalhousie University, Memorial University of Newfoundland, and the University of Prince Edward Island, represents Canada's most significant concentration of ocean science research capacity. Its work spans ocean climate systems, marine biodiversity, blue economies, and the ocean's role in carbon sequestration. This research base has commercial applications in ocean monitoring technology, autonomous underwater vehicles, marine environmental assessment, and fisheries management tools that are increasingly in demand globally.
Nova Scotia's tidal energy sector, centred on the Bay of Fundy, has made Canada a world reference point for tidal stream energy technology. The Bay of Fundy has the world's highest tidal range, and the Fundy Ocean Research Centre for Energy (FORCE) has been testing in-stream tidal energy devices since 2009. The technology development pathways pioneered at FORCE, including the engineering challenges of operating in extreme tidal environments, are being commercialized by Canadian companies and exported to tidal sites in the UK, France, and Southeast Asia. This is a niche but genuine Canadian technology export story that receives almost no mainstream trade coverage.
Arctic shipping represents the ocean economy's most strategically complex dimension. As northern sea routes become commercially viable, the Northwest Passage's potential as a trade corridor intersects with Canadian sovereignty claims, Indigenous governance in the territories, and the defence and environmental implications of dramatically increased marine traffic in a fragile ecosystem. The commercial interest is real: a Northwest Passage route between Asia and Europe would be significantly shorter than either the Suez or Panama Canal routes. The governance questions, including who authorizes transit, what environmental standards apply, and how revenues from shipping activity would benefit northern communities, are unresolved and consequential.
Canada claims the Northwest Passage as internal waters. The United States and most maritime nations treat it as an international strait. This disagreement, unresolved since the 1969 voyage of the SS Manhattan, has moved from a legal abstraction to a commercial question as Arctic sea ice declines. The passage was navigable for approximately 24 days in summer 2024 without icebreaker assistance — a figure that has increased from near-zero in the 1980s and is projected to reach 90–120 days by 2050 under current emissions trajectories.8
The commercial implications are significant. A viable Northwest Passage route between the Pacific and Atlantic would reduce shipping distances between East Asia and Europe by approximately 7,000 kilometres compared to the Panama Canal route, cutting transit time by roughly eight to ten days. For Canadian shipping — particularly for Arctic resource extraction and resupply — it would connect remote communities and industrial sites to southern markets at dramatically lower cost. For Canada's position in global trade, it would make Canadian Arctic ports and infrastructure strategically valuable in ways they currently are not.
The Canadian Armed Forces' Arctic and Offshore Patrol Ships (AOPS) program, which delivered HMCS Harry DeWolf and subsequent vessels, represents the most significant naval investment in Arctic sovereignty in a generation. The Nanisivik Naval Facility on Baffin Island provides a refuelling and docking capability that did not previously exist. But Canada's Arctic icebreaking fleet remains aged and insufficient for the level of commercial activity that a warming Northwest Passage will generate. The Canadian Coast Guard's polar icebreaker CCGS John G. Diefenbaker, under construction, will be the first new heavy icebreaker in the fleet since 1988.9
The Inuit Circumpolar Council and individual Inuit Nunangat organizations have consistently asserted that Inuit peoples must be central to Arctic governance decisions, including decisions about Arctic shipping routes that pass through or adjacent to their communities. The Nunavut Agreement provides for Inuit participation in land and resource management, but its provisions were not designed with commercial shipping in mind. Developing governance frameworks that respect Inuit self-determination while enabling responsible commercial activity is the central policy challenge of Arctic economic development.
Canada's offshore oil and gas production is concentrated in two basins: the Scotian Shelf and the Grand Banks of Newfoundland and Labrador. The Hibernia, Terra Nova, White Rose, and Hebron platforms in Newfoundland represent approximately 100,000 barrels per day of production, declining from a peak of 350,000 barrels per day in 2007. The province's offshore revenues have funded a significant share of Newfoundland's public services for two decades, and the decline in production is a structural fiscal challenge that the province has not fully addressed.10
The contradiction at the centre of Canada's offshore energy policy is this: the federal government has committed to reaching net-zero emissions by 2050, while simultaneously approving offshore oil and gas projects whose production timelines extend well past that date. The Bay du Nord project — a deepwater project approved in 2022 by the federal government over the objection of environmental groups — is projected to produce oil through the 2050s. The federal Impact Assessment Act review that approved Bay du Nord found that the project's lifecycle greenhouse gas emissions were not inconsistent with Canada's climate commitments on the grounds that global oil demand will remain through the transition period and Canadian production displaces higher-emission sources. This logic — sometimes called the "high-quality barrel" argument — is contested but has been accepted in federal regulatory decisions.
Nova Scotia's offshore sector is at an earlier stage. The Scotian Basin Exploration Project involves drilling in an area that has not been commercially developed, and results have not yet established commercial viability. The Nova Scotia Offshore Energy Research Association (OERA) tracks basin potential and supports transition research. The province's renewable offshore energy potential — wind in particular — may ultimately represent greater long-term value than its hydrocarbon resources, though the infrastructure and regulatory frameworks for offshore wind in Atlantic Canada are at an early development stage compared to the North Sea and US Atlantic coast.
The Canada-Nova Scotia Offshore Petroleum Board and the Canada-Newfoundland and Labrador Offshore Petroleum Board are the joint federal-provincial regulatory bodies that govern offshore energy development. Their mandates were designed for oil and gas and are being adapted, imperfectly, to cover offshore renewables. The Canada Offshore Renewable Energy Regulations framework, still under development as of 2026, will determine how offshore wind projects in federal waters are approved and what revenue-sharing arrangements apply between the federal government and Atlantic provinces.
