The Canadian system is different and much better than the British one imo.
While both are single payer, the Canadian Medicare is federalized so Vancouver Island can target its members in a manner different than Fraser Valley.
The NHS is much more top down, and the facilities seem less updated than in Canada.
Salaries also largely kept up for medical professionals in Canada compared to the UK (and plenty of BMA members have begun moving to Canada for that reason).
When I was a kid on Vancouver Island, it wasn't uncommon to see Brits doing specialized work (eg. Doctors, Skilled labor, Civil Service) because they'd get paid way more and spend way less than in the UK.
At no point in his various medical emergencies did he need to wait 10 months for a CT scan... Or any other life-saving treatment.
