Doctors appear to have made a number of deals..

Some doctors  chose to practice in Canada because the taxpayer pays their insurance for malpractice lawsuits.

"... when doctors get sued they turn to the CMPA to defend them. And aggressively defend them it does....Ontario taxpayers pay over $100 million a year in CMPA premiums...there’s no deductible or co-payment by doctors on claims....the premiums, or membership fees, don’t increase if a doctor suffers one or even multiple claims... there are no limits on the insurance.

The doctor use the best legal talent money can buy with taxpayer funds, the injured person must make do with whomever he or she can afford...There’s no penalty for doctors who violate the standards of their profession.
There’s no deductible and no fee increases no matter how many claims are made against a doctor."
