A Toronto law firm is seeking judicial review of the Canadian government’s controversial decision to grant a special export permit allowing Siemens Canada to send back to Germany repaired turbines for use by the Nord Stream 1 pipeline, which is majority owned by Russian state energy company Gazprom.

The Federal Court application argues that issuing the permit is contrary to Canada’s sanctions regime imposed after Russia invaded Ukraine. The judicial review application filed by lawyers Monique Jilesen, Katelyn Leonard, and Scott Rollwagen of litigation boutique Lenczner Slaght is on behalf of the Ukrainian World Congress, an international nongovernmental organization representing the interests of Ukrainians worldwide, and Daniel Bilak, a Canadian citizen and resident of Ukraine.
