Some perspective on doctors moving to different countries. I selected a few quotes from the article, which concerns Ontario.

If Canadian-educated doctors who were born in the United States are eliminated from the statistics, the number practicing in the United States goes down to one in 12.

The tide is turning, however. In 2004, the number of Canadian-trained doctors returning to Canada outnumbered those leaving – 262 left and 317 returned.
Blayney himself was lured away from his country of origin – Ireland – to work in Canada in 1988.
"They (Ireland) lost me, along with maybe about 10 percent (of doctors) at the time," said Blayney.
"It was a time when a lot of people left and they didn't come back. It still happens now. There is a movement of doctors."

Blayney isn't too concerned his students will want to work in the United States. NOSM students are mostly from Northern Ontario and many want to stay here and help alleviate the doctor shortage, he said.

Some medical graduates go to the United States so they can earn a lot of money to pay off their debt load, he said.

"One of the important things is to make sure there are good bursaries and that tuition fees aren't rising excessively, and the debt that they have after four years of student life is less than $100,000," he said.
