On January 30, the Canadian foreign ministry (Global Affairs Canada) announced that another of its diplomats in Havana had fallen mysteriously ill. 
This is the 14th such case. “To date, no cause has been identified.” As a result, Canada is removing up to half of its embassy staff.
The Canadian statement added, “Canada has a positive and constructive relationship with Cuba. We have had close cooperation with the Cuban authorities since the health concerns of our employees posted in Havana first surfaced in the spring of 2017.”
Cuba’s Ambassador to Canada, Josefina Vidal, said Cuba “understands the obligations of the government of Canada to protect its diplomatic personnel in any part of the world, and to try to find answers to the health symptoms reported in Cuba, [which] remains committed to preserving the good state of relations and expanding its ties with a country to which strong ties of friendship and cooperation unite us.”
Nevertheless, the Cuban Ambassador found the Canadian decision to reduce its Havana Embassy staffing “incomprehensible.” It does “not help solve or find answers to the health symptoms that diplomats have reported and will have an inevitable impact on the conduct of relations.” Instead, this decision “favors those in the United States who use this issue to attack and discredit Cuba. It is known that individuals with a high responsibility for foreign policy in the United States are committed to provoking a climate of bilateral tension and being able to point Cuba as a threat.”
