Interesting thesis,
If you start out with a bias towards one system or another, why would anyone put any stock in your conclusion? Any "results" you might espouse have already been tainted. It is imperative that system comparators and relative benefits be examined constantly, regardless of the industry. That is how organizations grow and improve. It is equally imperative that all members of an organization be involved and have an opportunity for input. These groups of individuals, from the political end, from the management ranks, to comm officers, to paramedics are tasked with providing the best service to the patient, in whatever environment they find themselves in. All have different roles, but are, theoretically at least, working toward the same goal. For a "research" paper to arrive at a conclusion as to what is "best" (although you have already made up your mind) involves thorough, objective and broad information gathering, and a solid, inclusive assessment of that information.
Consider.......
Municipal systems have advantages in responsiveness to the community that provincial systems do not.
Provincial systems have economies of scale and an ability to standardize equipment and performance that municipal systems do not.
Provincial labor issues have a generic flavor that does not generally account for local practices or conditions.
Municipal labor issues lack a recognition of what are generally provincial credentials.
The point is that "better" is a nebulous concept, which cannot be categorically established by the narrow, biased focus of your thesis.
