Moscow is warning that relations with Canada are on the verge of being severed after the Trudeau government moved to forfeit a massive Russian cargo plane.

On the weekend, Justin Trudeau visited Ukraine where he announced that Canada officially seized an airplane that had been sitting on the tarmac at Toronto’s Pearson Airport since last February .

Russia’s foreign ministry says Moscow is prepared to retaliate and the decision  will involve the most serious repercussions for Russian-Canadian relations.

Canada is the first G7 country to enact a law that allows Ottawa to not just seize assets held by sanctioned people, but to forfeit the money and have it diverted to victims.

Ottawa plans to begin the process to forfeit the plane and use the funds to support Ukraine, which could be the government’s first use of that law.
