What is the test for loss of housekeeping?

A decision of this Court in Thibert v. Zaw-Tun, 2006 ABQB 423, 64 Alta. L.R. (4th) 41, at para. 251 sets out the law regarding loss of housekeeping: The validity of loss of housekeeping claims is now clearly established and the approach to such claims is guided by the following four principles: (a) homemaking services are recognized as having pecuniary value even though they are provided outside the money economy; (b) the loss of homemaking capacity is a loss of the plaintiff himself, not his family; (c) loss of homemaking capacity is compensable even if it is not replaced by purchased services; and (d) loss of homemaking capacity is compensable even if family members “pick up the slack” and do the missing tasks.
