I know with many of you the term "union" is a very bad word. However, by being an IATSE member, I receive full medical coverage paid by my employers. The only cost that I incur is my union dues. Otherwise, the members receive Blue Cross for major medical, Delta Dental and VSP for optical. It is the best insurance package that is offered by employers anywhere. So there is a positive view for becoming union. And with over 6000 members just in the camera guild alone, joining is not that hard and would help stamp out the abusive non-union producers who make all of the money and give absolutely nothing back to the employee.
As for Canadian medical, I was in a Vancouver, BC emergency room a couple of years ago and was appalled at the quality of service. I found the entire system over-burdened with people who did not need emergency attention and were not discouraged from taking up space from those who truely needed it since it does not cost anything. Doctors could not spend any quality time with their patients since the waiting line is so long. Emergency rooms are crowded here in the US as well but under control when compared. I also understand that specialized medicine is not readily available in Canada and most come to the USA for major proceedures.
