Polite people get screwed, no matter what country they're in.
Should you have begun to scream obscenities at the top of your lungs, the situation would have been dealt with much faster.
I had to have an endometrial biopsy once. The painful cramps literally bent me in half. I kept my humor and said "this is your idea of 'disomfort'?" (OK, their first mistake: not laughing at my joke. That doesn't bode well for people. If I can keep my shit together enough to be funny while in agony, you'd best laugh at the damned joke.)
I promptly went into shock. My blood pressure dropped nearly off the scale; cold sweats; trembling...the entire list of actual medical shock symptoms. (People die from shock. I've taken a couple of first aid classes.) I had the nurse get my husband out of the waiting room. The doctor spent the entire time babbling "I've done hundreds of these procedures and this has never happened before!" OK, even while going into shock I can recognize a "cover my ass, blame the victim" defense.
I fired his ass. The first time I fired a doctor it was one of the most liberating experiences of my life. I don't know what, if anything, you can do in Canada, but here...it's important to remember exactly who pays whom. As far as I'm concerned, these people work for ME.
The best doctor I've ever had is my "back doctor." (Rhematology, fibroymyalgia...and gave me the only anti-depressant that's ever done me any good.) His first name is Oleg.
My new primary care physician, whom admittedly I've only seen once, is so far most satisfactory. His first name is Yaroslav.
Apparently, Russian medical schools have a class or two in "being thorough" and "how to actually give a shit about your patient."
