I can provide you with an indication of uptake.
For the multi-unit sector, since 2010 through the early days of 2018, the number of apartment buildings—we call them files—that have been through amounts to 181 projects, and we've refunded close to $7 million. This is across about 17,500 dwelling units. If you take those figures, you'll see that we've provided, per dwelling unit, about a $400 refund for the property owners in those units on that side.
On the single-family homes, between 2012 and 2017 we had 4,200 houses through the system. The total refund was about $5.4 million, which amounts to about $1,200 per application.
