Little is known about nurses who leave Canada to work in the US. The main purpose of this study is to gain some insight into the emigration component of nursing supply and demand by comparing characteristics of nurses who left Canada to nurses who stayed. Specifically, Canadian-trained RNs who work in the state of North Carolina are compared to RNs who work in Canada. Results show that there are 40% more Canadian-trained RNs in North Carolina than there are in Prince Edward Island. A higher percentage of Canadian-trained RNs in North Carolina are male, under 40 years of age, have baccalaureate training and graduated less than 10 years ago. Canadian-trained nurses in both countries have very low rates of unemployment. The loss of Canadian-trained RNs to the US is a significant problem, and there is an urgent need to obtain a better understanding of why nurses leave the country.
