Ottawa — A senior adviser to Prime Minister Mark Carney has warned that unregistered Russian oil tankers evading international sanctions could one day trigger a major environmental disaster in the Arctic if left unchecked.
Speaking at a Polish Embassy panel in Ottawa earlier this month, David Angell, the Prime Minister’s foreign and defence policy adviser, called the rise of illegal “shadow vessels” a “terrifying prospect” for Arctic safety. “The idea of illegal, substandard, uninsured vessels transiting through High North and Arctic waters was, is, and remains a terrifying prospect,” Angell said.
Canada and its G7 allies have blacklisted over 400 shadow ships in just six months — vessels that often operate with false flags, no insurance, and poor maintenance to smuggle Russian oil in violation of sanctions imposed following Moscow’s invasion of Ukraine.
The initiative is designed not only to cut off Kremlin oil revenues but also to protect fragile northern ecosystems from potential oil spills or collisions involving unsafe ships.
Experts at the panel described a cat-and-mouse struggle to track and sanction vessels that frequently change names, flags, and ownership to avoid detection. “They can easily re-enter the system even if sanctioned — under a new name, under a new flag, under new ownership,” said Elzbieta Kaca of Poland’s Institute of International Affairs.
Anna Kostrzewa-Misztal, a senior official with Poland’s foreign ministry, praised Canada for pushing the G7 to crack down on these ships. “It wouldn’t be possible without Canada,” she said, calling Ottawa an “important pillar” of the global effort.
Countries including Denmark, Finland, and other Nordic and Baltic nations have joined the campaign, which involves maritime surveillance, intelligence sharing, and coordinated blacklists of suspected Russian-linked vessels. Finland’s Ambassador to Canada, Hanna-Leena Korteniemi, warned that uninsured Russian tankers pose a “dual threat” — both ecological and geopolitical — as they skirt through congested northern shipping routes near Helsinki, Stockholm, and Copenhagen, sometimes using GPS jamming to evade detection.
Mitchell Robitaille, of Global Affairs Canada, who co-leads the G7 task force on Russia’s shadow fleet, said the work is ongoing. “As much as we want to be ahead, when it comes to enforcement, we’re often one step behind,” he admitted.
He added that Canada is helping small or vulnerable countries avoid becoming “safe havens” for re-registered Russian vessels by offering technical assistance and diplomatic support to strengthen their maritime oversight systems.
Analysts believe these coordinated sanctions are already working: sightings of Russian “shadow” ships in European waters have declined, and international pressure has pushed countries like Panama and Barbados to revoke Russian vessel registrations.
Still, experts warn that continued vigilance is essential. “These ships not only fund Russia’s war but risk catastrophic pollution in some of the world’s most delicate waters,” said Kaca. “The shadow fleet is shrinking — but the danger remains.”
