  • •Canadian diplomats reportedly engaged in espionage in Cuba from 2016 to 2018.
  • •Alleged sonic attacks linked to Russia were reported by diplomats during this period.
  • •The Canadian government is restricting disclosure of information related to the espionage operations.

Reports reveal that Canadian diplomats were involved in espionage activities in Cuba on behalf of the United States between 2016 and 2018, coinciding with incidents of alleged sonic attacks affecting diplomats. The Canadian diplomats reportedly used satellite equipment smuggled into Cuba by the US. Symptoms experienced included headaches, dizziness, and memory loss, which were initially attributed to sonic attacks linked to Russia. However, a 2023 US Intelligence Community analysis suggested that these symptoms were likely due to preexisting conditions and environmental factors, not foreign interference. The Canadian government has invoked Section 38 of the Canada Evidence Act to restrict disclosure of details related to a lawsuit from affected diplomats. This espionage operation is part of a historical pattern of Canadian support for US intelligence activities in Cuba, dating back to the 1960s. The ongoing US blockade of Cuba has exacerbated the humanitarian situation on the island, affecting millions.
