Recently, payments to your physicians by PHRMA and device makers have been made public. That's good news. The bad news is that it is damnably difficult to access this information. There appear to be many firewalls. Suffice it to say, many physicians in the US are on the take. It may even be worse in Canada. It must be the same everywhere expensive drugs and treatments are utilized.
Here are links to the recent New York Times articles about this new database.

I found the government site difficult to navigate.
However, the Dollars for Docs web site was much simpler and gives similar information.
These sites probably underreport payments, but they still have meaningful information.
