As a Canadian in the healthcare field perhaps I can chime in as well.
When you talk about Canadian healthcare, it is a provincially run program (not federal) so let's talk about it at the provincial level. As I am an Ontario resident I'll be discussing this from an Ontario perspective, talking about all of the provinces and their differences would entail several posts.
Ontaio is currently going to institute (or plans to at least) pay freezes on physicians due to the rising cost of healthcare in a non-booming economy. However it is currently one of the best provinces in wait times. The provincial median is 6.7 weeks to see a specialist after being referred and another 7.1 weeks to being treated. This has increased 3 years compared to last year and about doubled from 20 years ago. For some specialties like orthopaedics the total duration is ~40 weeks. This is in contrast to the US where ~90% see the specialist within 4 weeks. Internationally we are considered to be amongst the worst nations when it comes to wait times.
Another big problem with the Ontario system is unemployment. 1/3 specialists, especially surgeons, are unemployed due to a lack of operating rooms and jobs available - even in rural areas. There is a definite need but with the single payer system we have, the aging population pyramid, and increasing healthcare costs we have there is no money left to pay physicians - who make less on average (at least in the surgical specialties) than the US physicians. So we're graduating surgeons who can't work and are forced to go the US to find jobs.
To address one of Dr. Martin's comments btw, someone jwo develops a surgery/technique/game isn't always the best person at solving it. Developing a mitral valve replacement survey using MIS techniques doesn't mean you're the best person to technically achieve it (you could be, but it's not a given as she phrases it). The US has a system that rewards exceptionalism and excellence, the Canadian system generally rewards mediocrity (this is even evidence in other fields such as law and even academia). The US is famous for having premier surgeons and state of the art equipment. A prominent example I know is in the field of limb lengthening, where until very recently there was not a single surgeon in Canada who could do internal limb lengthening, they all used the external fixator pioneered in the USSR. Even in medical education you are seeing prominent US schools teaching the use of hand held ultrasound devices which are supposed to one day replace stethoscopes. The US also has far more specialized medical fellowships focused on advanced techniques and tools such as using tne da Vinci robot system.
I can provide references if necessary (I typed this up on my phone) but most of these facts are readily google-able.
TLDR: Our system isn't as perfect as you might think and is actually teetering on financial instability at the moment with up to 1/3 new physicians unable to find a job in the country due to funding issues.
