OTTAWA - Ukrainian-Canadians are pushing some of the world's bigger powers to convince Russia to remove its grip on Ukraine's Crimea region.
Dozens of protesters marched in Ottawa today in front of the embassies of China, France, the United States and the UK.
They urged the signators of a 1994 nuclear disarmament agreement with Ukraine to live up to the accord.
The Budapest Memorandum on Security Assurances was originally signed by Russia, the U.S. and the United Kingdom, giving Ukraine assurances of protection in exchange for giving up its nuclear weapons.
China and France later gave assurances that they would also live up to the accord's provisions.
But an advisor to Russian President Vladimir Putin on Thursday suggested the accord could actually be used by Russia as justification for sending troops into Ukraine to protect people in the Crimean peninsula.
