This is generally not my experience in Ontario. I've been to my family doctor and the ER multiple times during COVID and after and although the ER can be a multiple hour wait for minor things like a fever it's still pretty speedy for serious injuries. I haven't needed any elective surgery but checkups like heart ultrasounds were still only a week or two wait.

If anything, my dentist has been the most impacted by COVID. They're booked solid for at least a month to six weeks.
