Canadian Active Living Environments 2.0: Development of an open-source pipeline for the replication and extension of the Canadian Active Living Environments measure

The Canadian Active Living Environments (Can-ALE) project was developed in 2019 to provide a standardized, pan-Canadian indicator of how supportive neighbourhood built environments are for physical activity and active transportation, enabling comparisons across places and over time. Can-ALE 1.0 produced measures for the 2006 and 2016 census years, but it did not include 2011 or 2021. As well, the data and processing steps were not packaged in a fully reproducible format, limiting longitudinal analyses and replication. In this study, the original measure was replicated and extended by developing Can-ALE 2.0, an open-source, reproducible R-based workflow to generate Can-ALE metrics for the 2011, 2016, and 2021 census years.
