I can answer the question.
It's helpful to understand how employment support programs work. In terms of the stimulus package for the hardest hit businesses, the criterion of having suffered a drop in income in a particular month compared to another month certainly comes from the old wage and rent subsidy program. This is the measure that was established at the beginning of the pandemic. It's been in the program since the beginning and it's very well understood by employers. So that criterion is pretty clear.
In practice, this means that businesses must demonstrate a loss of income in the current month. The government chose this criterion in order to target the hardest hit businesses. In this way, there is no change in the rules compared to those previously in place. This measure would also apply under the new program.
