maybe they should sue the hospital for false diagnosis, since the Canadian hospital found the real problem so easily.
That was my thought.
I really feel for these people. Something like this can ruin your life. Were it me I would take a good look at a Law Suit. If nothing else it might convince them the to void the bill.
I can see the insurance company's point too; They would have refused to insure them at all if they had answered the questions correctly. The policy is a legal document, in fact a contract. You can't just say "I didn't realise" or "I thought" or "I didn't know". You have to take the time, often more than a day, to thoroughly read and understand the contract.
Hope it works out for you.
