Frankly (and maybe it's different in Canada), but I feel like people will have better health outcomes if they are aware of the options and consult, work with, and even challenge if need be, their GP.

GPs (or Primary Care Physicians, PCPs in the U.S.) share some goals with their patients, but many goals are not shared:

* Spending less money / good drug success / less side effects vs. using only tests/drugs they GP is comfortable with * Avoiding lawsuits vs. candid discussion * Taking time to research medical hypotheses vs. needing to get to the next patient

Come to think of it, if one is willing to invest the time, have an inquisitive mind, and demand a partnership relationship with most service providers, perhaps that person will generally have better outcomes in many areas (home repairs, dental, car service, etc.).
