For sure, mine can take an hour to call you back. If it is urgent you go to Emergency. The clinics are for walk-ins as far as I know, not sure if they take appointments, and for the same kind of things you might see your doctor for. We also have a free health line where you can call and talk to a nurse. When it's all paid by the provincial insurance, you choose whatever one works.
I think the biggest reason our costs have been moving higher is because the baby boomers have hit retirement age, but we are pretty unaware of costs since we never see a bill. An older population just uses the doctor more.
