Thank you.
On the way the wage subsidy is structured, you're of course correct that the first reference period, from March to March or using some other metric that's allowed by the legislation, requires a 15% drop in revenue. There is a rule in the framework legislation that essentially deems that you qualify in the second period if you qualified in the first period. The purpose of that rule is to provide added certainty to an employer so you don't get fluctuating in and out. That would automatically qualify you for the second period. If a business didn't qualify in the first period but qualified in the second period, it would be deemed qualified in the third period.
There is a smoothing mechanism in there that helps deal with the risks you identify.
