As a Canadian I'd echo these comments and wouldn't even remotely consider moving an aged parent with failing health out of Canada where he/she has health insurance to a country where he/she won't without great additional cost. Any mistake and this could cost you and everything your mother owns, and then some. JMO, but this is a terrible idea.
