  1. aThe dollars value of sales are expressed in January 2020 constant dollars to adjust for inflation
  2. bChanges in the dollar value of sales were adjusted for seasonal trends (categorical variable for each month) and for differences between the 6 provinces (categorial variable for each province)
  3. cReference = pre-pandemic period January 2010 – February 2020. Positive numbers indicate an increase in per capita sales, while negative numbers indicate declining sales
