Salon.com reports that American immigration to Canada may be increasing (see Salon.com Life | Discontented Americans consider Canada).
It's amazing how irrational human beings can be. Most cite Canada's health care system as a positive reason for immigrating, and yet until recently hospitals in Toronto were one of the best places in the world to catch SARS. Others like Canada's gun control laws, and yet in recent months Canadians have been up in arms (excuse the pun) about the country's exceedingly expensive gun control registry. One Minnesotan even wants to go for the Canadian climate! She dreamily described Vancouver as "Green all year, no mosquitos".
Given that more Canadians continue to move to America each year than vice versa, I guess the grass really is always greener on the other side of the fence.
