Moscow considers Canada's sanctions against Russia illegal and will take retaliatory measures, Kremlin spokesman Dmitry Peskov said, Sputnik reports.
When asked whether Russia would respond to Canadian sanctions against Russia, Peskov answered in the affirmative.
"We will", he said, adding that these sanctions were illegal.
