This article points out a few aspects that are not often talked about.
For every dollar of extra billing by a private for profit clinic, the federal government claws back an equal amount from its cash transfers. In 2015-16, that amount was $15.9 million, enough for 53,000 MRIs.
So effectively, we all pay for the extra billing.
(Cash transfers are the payments that every province and Territory receives from the Federal government for health care.)
B.C. is the only province that Ottawa has repeatedly fined for unlawful extra billing.
I believe that there is a misconception that private companies will be forced to close; this is incorrect, they can continue to operate as long as they follow the law.
