President Petro Poroshenko has sent his best wishes to Canadian Governor General David Johnston to mark his country's national holiday, Canada Day. "Today, when Ukraine is fighting an unprecedented for a European state in the 21st century fight against an aggressor protecting its own sovereignty and territorial integrity, constant and decisive support from Canada is especially important," Poroshenko said, inviting Johnston to visit Ukraine and expressing hope that they would have a personal meeting in Kiev in 2015.
