Ottawa - Canada is imposing sanctions against top Russian oil firm NK Rosneft OAO and the head of conglomerate Rostec, among others, in response to the actions of Russian-backed militants in Ukraine, Ottawa said on Tuesday.
In all, Canada - which said it was acting in coordination with the European Union (EU) and the United States - imposed sanctions against 37 Russian and Ukrainian individuals as well as 17 Russian and Ukrainian entities.
Prime Minister Stephen Harper, who has taken a hard line in public against President Vladimir Putin over what he calls blatant Russian interference in Ukraine, said Canada was ready to take more steps if needed.
