I've had a couple of exposures to emergency rooms and clinics over the last few years. The most telling was when I sliced open the back of my hand with an industrial fan. We cleaned and bandaged it, then applied ice, and I sat until the pain subsided and felt good enough to go the nearest clinic.
By the time I arrived, the pain and nausea had returned, but no biggie. I presented my healthcard and described the situation, which caused the three people behind the counter to pause and eye me as one asked "But you didn't break the skin, right?"
I did not get a chance to complete my reply, which started with "Yes, of course...". "Drop your card, come with me now".
The waiting room was more than half full, but I was priority number 1 for the next 15 minutes. A nurse carefully, delicately removed the dressing, then used a thin metal instrument to ever so carefully widen the cut and examine the tissue underneath. When satisfied, she sent me back to the waiting room where I sat for an hour and half.
I learned the full story when I returned for an x-ray the next day (I hurt myself on a Sunday, the basement x-ray lab was closed): Had I severed - or even cut - any of the tendons leading to my fingers, I would have rushed to the hospital to save my hand before the tendons shrank and dried into uselessness.
I didn't mind the 1.5 hour wait on the Sunday, or the combined 1.5 hours on the Monday, because when it came to what really mattered, there was no wait at all.
They only took my healthcard once the initial careful inspection was over. Billing and bean counting were irrelevant.
Note: I expect that billing for treatment of visiting foreign nationals will vary widely by province (anyone in the know care to chime in?), but that the overall triage process will be similar.
