"forbid doctors who bill the public system from also charging patients to access any type of medically necessary service."

All those anecdotal patient stories : cataracts, vein stripping, VIP physicals, Work related  shoulder bursitis and CT scan for tension headache are NOT medically necessary in terms of an emergency threat to patients life and limb. It is poor journalism to then repeat what biased advocates claim by adding in a lot of unverifiable sob stories about the elderly going bankrupt allegedly directly due to those evil double dipping physicians.
This entire series of articles is nothing but physician abuse and scapegoating physicians for the imploding and underfunded bankrupt Canadian health care system. It's a complete distraction from the true reasons for why the Canadian system is underfunded by $Billions and $Billions.
