Lastest update on DAN Insurance for Canadians diving in Cuba: DAN Europe & DAN Asia have gotten back to me and have confirmed that their respective insurance policies cover diving in Cuba. However, Canadians cannot buy DAN Europe Insurance or DAN Asia Insurance as we are not residents. Canada falls under DAN America and so far, neither DAN Asia nor DAN Europe can get anything from their American colleagues in respect to Canadians being covered in Cuba. (Which is very misleading as a large number of DAN insurance is sold in Canada to Canadians planning their Cuban dive vacation).
The best bet? Get separate insurance (preferably from a non-American interest company which itself is hard these days) for Cuba, and make sure Cuba is specifically written into the policy.
Another option for those with multiple residency, would be to buy DAN outside of DAN Americas.
On another interesting note:
should something bad happen, the dive operation can call DAN medical for advice as non-profits, research & education do not fall under the US embargo which is purely an economic embargo. The DAN line is drawn when there is money involved, i.e. chamber charges, emerg evac, individual insurance.
