Human Rights Watch, a nonprofit, nongovernmental human rights organization, wrote a letter to Prime Minister of Canada Justin Trudeau regarding his July 11-12 visit to Ukraine. "We trust that you see the visit as an important opportunity for Canada to raise human rights concerns with President Petro Poroshenko and other senior officials. We write to outline a few key concerns regarding Ukraine that we hope you will discuss during your trip," reads the letter, released on the organization's website on July 12.
