The statement comes days after a group of 14 Canadian diplomats sued Ottawa for $28 mln Canadian dollars ($21 mln). According to them, the government had put the diplomats and their families at risk, withholding information on the matter and interfering in their ability to seek medical help.
The unusual illness was first reported by Canadian Embassy employees in Havana in 2016, with the last confirmed case being in November 2018.
