Inconvenient truths

Somebody went and looked at the evidence rather than taking the usual trumped-up claims about Canadians buying health care in the U.S. for granted. And those looking for excuses to gut Canada's public health care system aren't going to like the results:

This study was undertaken to quantify the nature and extent of use by Canadians of medical services provided in the United States. It is frequently claimed, by critics of single-payer public health insurance on both sides of the border, that such use is large and that it reflects Canadian patients’ dissatisfaction with their inadequate health care system. All of the evidence we have, however, indicates that the anecdotal reports of Medicare refugees from Canada are not the tip of a southbound iceberg but a small number of scattered cubes. The cross-border flow of care-seeking patients appears to be very small.

Our telephone survey of likely U.S. providers of wait-listed services such as advanced imaging and eye procedures strongly suggested that very few Canadians sought care for these services south of the border. Relative to the large volume of these procedures provided to Canadians within adjacent provinces, the numbers are almost indetectable. Hospital administrative data from states bordering Canadian population centers reinforce this picture. State inpatient discharge data show that most Canadian admissions to these hospitals were unrelated to waiting time or to leading-edge-technology scenarios commonly associated with cross-border care-seeking arguments. The vast majority of services provided to Canadians were emergency or urgent care, presumably coincidental with travel to the United States for other purposes. They were clearly unrelated either to advanced technologies or to waiting times north of the border.

H/t to Paul Krugman, who also notes that the real southern flow of patients seeking care they can't get at home is from Americans seeking lower-cost care in Mexico.
