The move represents a dramatic policy shift toward alignment with Western allies, though the global sanctions count remains unchanged.
Canada announced sweeping new sanctions this week targeting 100 oil tankers linked to Russia’s so-called shadow fleet, marking the country’s most aggressive maritime enforcement action since the war in Ukraine began. But an analysis by maritime intelligence platform FleetLeaks reveals that every vessel had already been sanctioned by at least one other jurisdiction.
The addition raises Canada’s sanctioned vessel count from 310 to 410, yet leaves the global total at 867 ships — a sign that Western nations are moving toward coordinated enforcement rather than expanding their targets.
“Canada remains unwavering in its commitment to Ukraine’s sovereignty and its people, who are forcefully defending their rights in the face of Putin’s corrosive and aggressive actions,” Foreign Minister Anita Anand said Tuesday at a G7 meeting near Niagara Falls, Ontario. “Canada will continue to intensify pressure through sanctions in coordination with allies and partners until Russia puts an end to its unjustified invasion of Ukraine.”
Harmonization Over Expansion
The sanctions represent a sharp increase in Canada’s overlap with other G7 nations. According to FleetLeaks’ analysis, Canada’s harmonization rate with Australia jumped to 98.7%, with 153 of Australia’s 155 sanctioned vessels now also listed by Canada. UK-Canada overlap reached 71.6%, covering 390 ships, while EU-Canada alignment rose to 64.2%, spanning 360 vessels.
The lowest harmonization remains with the United States at 43.1%, though the two countries now share 201 sanctioned vessels.
For years, the European Union and United Kingdom have led vessel-specific sanctions targeting tankers involved in oil price-cap evasion, illegal ship-to-ship transfers, and deceptive shipping practices. Canada had largely focused on sanctioning individuals, entities, and financial institutions rather than maritime assets.
“This is the first time Canada has taken such a large step toward alignment with the EU, UK, US, Australia, and New Zealand on maritime targets,” according to FleetLeaks, which tracks cross-border sanctions data in real time.
Maritime sanctions experts say coordinated enforcement is critical to disrupting Russia’s shadow fleet operations.
“Given the strategic importance of the shadow fleet to Russia, a joint task force should be formed to share real-time intelligence on vessel movements, ownership, flagging, and insurance,” wrote Petras Katinas, an energy and sanctions analyst at the Centre for Research on Energy and Clean Air, in a recent Foreign Policy article. “Harmonized sanctions require little political capital but would deliver immediate results.”
Closing the Enforcement Gap
The shift closes enforcement gaps that Russia’s shadow fleet has historically exploited through jurisdiction shopping — reflagging vessels, changing ownership structures, and switching insurers to evade detection.
The shadow fleet, estimated at 1,200 to 1,600 vessels total, moves Russian oil and gas while evading Western restrictions. Only about 867 vessels appear repeatedly across official sanctions lists, suggesting the universe of confirmed targets is relatively finite.
“Unfortunately, a few shipowners, including in Western countries, undermine sanctions against Russia by selling their ships into the shadow fleet,” said Elisabeth Braw, a senior fellow with the Atlantic Council’s Transatlantic Security Initiative. “Shadow vessels pose hazards to other vessels, to the maritime environment, and to coastal states.”
The announcement aligns closely with sanctions introduced in October by the United States, the European Union, and the United Kingdom. In May, the EU adopted its 17th sanctions package, adding 189 vessels — what the bloc called “the largest single G7 sanctions action targeting shadow fleet vessels” at the time.
“Today’s package more than doubles the vessels that are part of the shadow fleet of oil tankers or contribute to Russia’s energy revenues,” said Maria Luís Albuquerque, European Commissioner for Financial Services, following that announcement. “The sanctions are working: Russia’s economy is under strain, its resources are dwindling, and its ability to sustain this illegal war is increasingly unsustainable.”
Beyond Vessels
Beyond maritime targets, Canada’s latest sanctions include 13 individuals and 11 entities tied to Russia’s liquefied natural gas sector, drone development, and cyber infrastructure. For the first time, Canada sanctioned entities that supply cyber infrastructure used in Russian hybrid strategies against Ukraine.
Ottawa says it has now imposed more than 3,300 Russia-related sanctions since 2014, including more than 400 vessels.
The coordinated approach reflects a broader G7 push toward unified maritime enforcement as traditional sanctions increasingly focus on supply chain disruption. Global insurers and protection and indemnity clubs now face consistent risk indicators across multiple jurisdictions, making legitimate coverage for blacklisted vessels nearly impossible.
Canada’s Department of Foreign Affairs did not immediately respond to requests for additional comment.
