How frustrating. Since you are seeing your family doctor on Monday, it seems that you can just wait for their referral at this point.
It certainly does seem that there are some tradeoffs with universal healthcare systems. In my case, my lesion was spotted by my dentist who referred me to the oral surgeon (same as you just saw). Since the lesion was only in the area of the tongue, he did a biopsy, but if it had been elsewhere, I could have actually even self-referred right to an ENT, as long as they were in my insurance network. Ultimately, when the biopsy came back positive, I was referred to an ENT, got in to see him 2 days later, and had surgery only 4 days after that. It all happened very fast once the DX was made.
