    Despite well-established health benefits, nearly half of adults in Canada do not engage in enough physical activity for optimal health benefits. In Canada there are differences in physical activity levels among immigrants and non-immigrants. The built environment has the potential to reduce or widen inequalities if its effects on physical activity differ among population subgroups. While evidence has highlighted potential differences in how the built environment is associated with physical activity across various population subgroups, some equity-seeking groups, such as immigrants, have received little research attention. Globally, most studies examining this association among immigrants have been conducted in the U.S., with inconsistent findings. The study presented in this thesis addresses these knowledge gaps, guided by two relevant theoretical perspectives, including the socioecological model and acculturation theory. The aim of this research was to generate novel evidence regarding the associations between the neighbourhood built environment, specifically objectively-measured walkability, and physical activity according to residency status (Canadian-born, recent immigrants, and established immigrants). Our objectives were 1) to estimate and compare TPA and LPA participation and duration between Canadian-born, recent and established immigrant adults and determine whether neighbourhood walkability accounts for any observed residency group differences, and 2) to estimate and compare the direction and magnitude of associations between neighbourhood walkability and TPA and LPA participation and duration between these groups. The study included cross-sectional analysis of nationally representative data from Canadian Community Health survey (CCHS 2017-2018) linked with 2016 Can-ALE data. We found that recent and established immigrants were more likely than Canadian-born to participate in TPA, but these differences attenuated after controlling for walkability. Moreover, recent and established immigrants were less likely to participate in LPA and undertook fewer LPA minutes, compared to Canadian-born individuals. However, the differences in LPA minutes attenuated after controlling for walkability. Walkability was positively associated with TPA participation and duration in all residency status groups, but the magnitude of these associations differed between these groups. Findings from this thesis suggest that improving neighbourhood walkability could have broad public health benefits, but tailored strategies are essential to address the needs of immigrant populations.
