This New York Times article (why can't the Chicago dailies beef up their staff to match the New York paper?) lays out the strain on Canada's publicly-funded, universal health insurance system. There aren't enough family doctors, especially in small towns.
Interestingly, the Canadian Prime Minister is meeting with the provincial premiers (like the President meeting with all 50 governors) in a televised three-day meeting on reducing waiting time for family doctors.
Somehow, I can't imagine the U.S networks broadcasting three days of meetings on improving access to health care between our governors and the president. Maybe those Canadians are just more civic than we are.
