There is one thing I find annoying, here in Alberta anyway, when you really need emergency services - an ambulance, you have to pay for it! This makes no sense to me what so ever, but once you are at the hospital you have no charges at all.
I do remember when this came about(many, many years ago) and the reason why(to cut down on people calling for one due to a slight cut, etc), but it still made no sense to me. I always thought if it wasn't a true emergency, like a cut artery etc., then you get charged, otherwise it should be covered like the rest of the system.
