What is the test for assessing damages on a replacement cost approach?

In assessing the damages on the replacement cost approach, the court must carefully scrutinize the gratuitous services done by the family member. A relatively minor adjustment of duties within a family will not justify a discrete assessment of damages: Campbell v. Banman, 2009 BCCA 484 at para. 19. In Dykeman at para. 29, Madam Justice Newbury cautioned that: Instead, claims for gratuitous services must be carefully scrutinized, both with respect to the nature of the services – were they simply part of the usual ‘give and take’ between family members, or did they go ‘above and beyond’ that level? – and with respect to causation – were the services necessitated by the plaintiff’s injuries or would they have been provided in any event?
