Welcome to Canadian health care! I've been waiting on a referral to a hand specialist for about 7 months now and my mom can't even get a referral regarding her dislocated jaw because they keep telling her GP that she has to go to her dentist to have it looked at and her dentist can't do anything about it (he's seen her three times regarding it!)
It'd deplorable you're getting that type of treatment. Do you live in a small area or a larger one? If you live in a larger area you may be able to find a family doctor who won't treat you so poorly. I live in a larger city in canada and had the luxury of shopping around for a family doctor, but when I lived in a rural area I had to take what I could get -- which meant 4 week waits to see the doctor (and I'm a T1 diabetic!)...a doctor who probably got her medical degree from the back of a cereal box.
I hope everything works out for you...I know sometimes we, Canadians tend to be a little too polite when it comes to healthcare (because the doctor always knows best!), but after seeing my psychologist who is American, I learned that it's OK to be forceful and your own advocate when it comes to the medical industry. As a result, I FINALLY received my PCOS diagnoses after 9 years of brush oRAB from gynecologists, endocrinologists, and various family doctors who blamed everything on my diabetes (which would've made sense if I was a T2 diabetic but I'm T1 and have had it since I was a kid!)
I wish you all the best -- perhaps going back to see this doctor who said your last two fingers aren't that important with some research from medical journals or back up that yes they ARE important might make her change her tune. Doctors aren't gods. My mom is an executive assistant. Without her pinky and ring finger she would be out of a job....so I'd say the pinky finger and ring fingers ARE quite important, if not for that situation, but just because ALL your body parts are important and should be functioning properly!!!
