The individuals, whose names were removed from a court record and do not wish to be identified, are collectively suing for $ 28 million in Canadian dollars, or $ 21 million.
The main claim of the prosecution is as follows: "Throughout the crisis, Canada played down the gravity of the situation, stored and concealed critical health and safety information, and provided false, misleading and misleading information. incomplete to the diplomatic staff. "
"The health and safety of our diplomatic staff and their families remains our priority," said a statement last week.
"The Canadian government continues to investigate the potential causes of the unusual health symptoms experienced by some Canadian diplomatic personnel and their families in Havana, Cuba." No cause has yet to emerge. been identified. "
According to the statement, after the last confirmed case of unusual health symptoms in November, a number of Canadian diplomatic staff in Cuba underwent additional medical tests.
And in April, Canada withdrew all non-core members of staff and family diplomats after the tests concluded that their diplomats also suffered from mysterious symptoms, including dizziness, ringing ears and a loss. of memory.
In the lawsuit, the group claims that the Canadian government has not taken its cases seriously and that the US government has moved faster to protect the welfare of its diplomats.
Canadian government officials did not comment specifically on the trial.
Canadian Foreign Minister Chrystia Freeland said on Tuesday that she was "really concerned" by the staff and that the group had "Canada's greatest sympathy and support."
"They were in Cuba to represent us and to represent our country, and their health and safety must be a priority," Freeland said.
Last week, the Canadian government declared that there was no evidence that Canadian travelers to Cuba are in danger.
Josefina Vidal, Cuba's ambassador to Canada, criticized Ottawa's decision to downsize staff, calling it "incomprehensible" that "feeds speculation" and said "this behavior favors those who, in the United States, use this issue to attack and denigrate Cuba. "
Vidal emphasized Cuba's cooperation in seeking out symptoms and affirmed the country's commitment to good relations.

A number of US diplomats and their families in Cuba said they heard strange noises in 2016 and 2017 and presented with symptoms such as dizziness, vertigo, pain and ringing in the ears.
The United States said 26 US diplomats and their family members were affected.
