Interrupted time series analysis using a spatial regression (spatial error model) framework for daily outflows from the two public health regions (PHRs; Toronto and Peel) moved back under tighter lockdown restrictions to PHRs under lesser restrictions during the 7 days before and after the second intervention on November 23, 2020 in Ontario, Canada. Mobility outflows and socio-economic covariates calculated at the aggregate dissemination area (ADA) level (n = 437).
