You're lucky to get treatment in 4 hours at urgent care. Where I live there is one clinic for over 100,000 people. You show up at 4am and that's usually too late. They regularly put up a sign on the door that says "Was are only seeing 10 people today. Go to the local ER if you need medical care." When you go there you can wait up to 2 days... or you give up and go home... or try in another nearby city.

My family and I save up our medical needs and get it dealt with when we travel. It's faster and easier to pay cash for medical treatment when we are overseas visiting family than it is here in Canada.
