Cuba has great economic difficulties because of the economic embargo that the U.S. has imposed on the country for over 50 years. The embargo was designed to "punish" Cuba for choosing a political system that the U.S. happened to dislike, and to put pressure to change that system, something the U.S. are usually experts at. It has not worked, however, --not even after the fall of the USSR-- but Cubans do suffer economic hardship. Pierre Elliot Trudeau was right in maintaining  normal relationships with Cuba, and I hope Justin Trudeau will continue in that path. No matter what one thinks of Cuba's communist system, you don't find there families living on the streets or in garbage dumps, like in Mexico or Brazil, nor violence and criminal gangs, like in Honduras and El Salvador.
