Known infections (KIs) over time in Ontario. Counts are split by whether or not the KI was resolved (marked as “resolved” or “fatal” in the Case and Contact Management database) by 16 February 2021 (see “Methods” section). Dashed vertical lines mark important dates for the outbreak in the province. Shaded regions indicate roughly when the most populous regions were in each reopening stage (reopening efforts have not been uniform across public health units). Larger stage numbers correspond to looser public health restrictions. Detailed descriptions of each reopening stage, recent shutdowns, and the newer zoned reopening framework can be found on the official Ontario COVID-19 website [16, 20, 25–28]
