D isparities in health and healthcare plague provinces' residents. This means that different subgroups of the population have differences in health and healthcare. Examples include socioeconomic status, location of residence and disability status. Disparities generate searching questions: does where you live, or who you are, affect your health or the quality or accessibility of healthcare you receive? It is important for provincial ministries of health and social care to address the issue of disparities. Disparities limit gains in health among the population, induce additional healthcare utilization or spending and lay bare inequitable distribution of public resources. Resolving disparities is often challenging as causal pathways may be complex, ingrained in communities or very expensive to address. Research on disparities is an important element of improving provinces' population health. Quantitative and qualitative researchers play complementary roles of observers and reporters of often-in-plain-sight disparities. Policy analysis plays the adjunct role of exploring intersections of legislation, strategy and program objectives and identifying short-and longterm options for decision-makers. In this issue of Healthcare Policy, several papers identify and examine disparities in access to healthcare services. Tobias and colleagues (2020) examine the effectiveness of cancer screening programs among First Nations peoples, Jones and colleagues (2020) report on gender differences in access to surgery, whereas Martin-Misener and colleagues (2020) explore facets of rural and remote healthcare delivery through the role of nursing practices. This issue also features an interprovincial comparison of childhood cancer costs by McBride and colleagues (2020), which provides valuable insights into variations in care delivery. Zoratti and colleagues (2020) report on a three-province comparison of drug reimbursement recommendations, whereas Bell and colleagues (2020) explore equity in
