If you compared wait times in Canada versus wait times in the U.S., Canada would probably be shorter overall.

The U.S. system creates artificial shortages in many different areas. They seek optimal profitablity by staffing slightly below what the need requires. This shortage justifies charging higher prices.

You can also probably blame some of the long wait times in Canada for things on the U.S. Specialist in the U.S. make a lot more money.
