The delegation's Twitter account Wednesday featured a map of Eastern Europe, with Russia in red and Ukraine, labeled "Not Russia," in blue, with the comment "Geography can be tough. Here's a guide for Russian soldiers who keep getting lost & 'accidentally' entering Ukraine."
Ukraine denied the soldiers were lost, as they claimed.
"This wasn't a mistake, but a special mission they were carrying out," Ukrainian military spokesman Andriy Lysenko said.
The Twitter comment came after Canadian Prime Minister Stephen Harper, visiting troops Tuesday in Arctic Canada, said the country was prepared for any Russian aggression via the Arctic.
"In Europe, we see the imperial ambitions of Vladimir Putin, who seems determined that, for Russia's neighbors, there shall be no peace...and because Russia is also Canada's neighbor, we must not be complacent here at home."
