I lost a Canadian friend to an easily treatable melanoma because his treatment kept being postponed until it was not longer operable.
I am sorry but I just don’t buy it. First off Canada doesn’t have socialized medicine. The provincial governments do take on government insurance but for only certain activities. There are a few private hospitals, mostly not for profit independent hospitals and people carry a lot of private insurance for drugs, dental and hospital rooms.
If a person has a serious issue the person jumps the que and gets looked after. Yes, there are delays in getting to see specialists and certain operations, however, it is no where near as bad as you suggest.
The biggest problem with the system is keeping the doctors as they can make more in the USA and the construction of PRIVATE long term care beds for sick seniors who take up to many hospital beds.
There are advantages to both systems in the USA and in Canada. Neither is perfect.
My best friend had a cardiac blockage while in Canada vacationing. It took three days to get what is done here always within three hours. He has a lot of work keeping his pilot’s license in place on his plane he built for retirement recreation.
