My province started billing for non-essential ambulance services years ago. I know they still get crap calls, but having to pay a minimum charge of $75 to get to the hospital deters some. Cabs are much cheaper, and as long as you promise not to spill anything they're more than willing to take you. Not knowing you're going to be charged for a ride until weeks after you've used the system helps too. And instead of implementing a whole new department to follow up on the billing I think government workers in an obscure office were told to do actual work in between games of solitaire! There's plenty of people who have whined and complained about their bill in the media, none would win citizen of the year however. Why is it that people don't learn how to behave unless you hurt their wallet? Sigh, I miss photo-radar...
