This research uses four nationally representative samples of time diary data, spanning almost 30 yr, that are fused with energy expenditure information to enumerate the median daily duration of moderate or vigorous-effort activity, quantify the prevalence of Canadians age 65 yr and older who are meeting recommended daily levels of physical activity, and explore the factors affecting rates of active living. Results indicate that 41.1% of older Canadians met recommended levels of physical activity in 1992, 40.6% in 1998, 43.5% in 2005, and 39.6% in 2010. Both rates of active living and daily duration of aerobic activity exhibit significant differences among sociodemographic groups, with age, sex, activity limitation, urban-rural, and season exhibiting the most significant influences. This study illustrates the potential for time diary data to provide detailed surveillance of physical activity patterns, active aging research, and program development, as well.
