Abstract Access to primary health care: Does neighbourhood of residence matter? For the degree of Master of Arts, 2009 Graduate Department of Geography University of Toronto Access to primary health care is an important determinant of health. Within current research there has been limited examination of neighbourhood level variations in access to care, despite knowledge that local contexts shape health. The objective of this research is to examine neighbourhood-level access to primary health care in the city of Mississauga, Ontario. Street address locations of primary care physicians were obtained from the College of Physicians and Surgeons of Ontario (CPSO) website and analyzed using geographic information systems (GIS). A 'Three Step Floating Catchment Area' (3SFCA) method was derived and used to measure multiple dimensions of access for the population as a whole, for specific linguistic groups and for recent immigrants. This research identifies significant neighbourhood-level variations in access to care for each dimension of access and population subgroup studied. The research findings contribute to a more nuanced understanding of neighbourhood-level variability in access to health care. ii Acknowledgements This research project has been highly collaborative in nature and there are a number of individuals involved who I would like to acknowledge.

In particular there is concern that access to primary care is decreasing and waiting times to see physicians are increasing. This has resulted in decreasing satisfaction with the health care system amongst the Canadian public (Sanmartin et al, 2000). Contributing to this problem is a reduction in overall physician numbers over the past decade in Canada. Peaking in 1993, physician numbers have steadily dropped by 5% since. Reasons for this possible physician shortage include federal funding cuts to the provinces, cuts in the enrollment numbers for medical school, an increase in specialist training at the expense of family doctor training, and a reduction in the number of foreign doctors entering Canada to practice medicine (Wharry & Sibbald, 2002). Given that approximately 4.1 million Canadians do not have a regular family doctor (Nabalamba & Millar, 2007), there are concerns that access to primary health care is an increasing problem. With fewer medical students choosing family practice, disparities in access to care are likely to increase in time as the existing group of family physicians ages and begin to retire. This is particularly problematic, given that the amount of primary care provision is directly associated with public health outcomes, including the prevalence of cancer, heart 1 disease, stroke, infant mortality, low birth weight, life expectancy, and self-rated health (Macinko, Starfield & Shi, 2007).
