The appellant disputed the existence of such a relationship, arguing that the parties maintained separate residences, did not cohabit continuously, and lacked financial interdependence. The respondent’s evidence included photographs, greeting cards, financial contributions to Somers’ home, and social media posts, which she argued corroborated her claim. The chambers justice found the respondent and Somers shared their lives, were emotionally committed, and functioned as an economic and domestic unit. He accepted the respondent’s evidence that 250 Mahogany was intended to be their joint home, noting the evidence of her financial contribution to the home. The chambers justice accepted this evidence and found the respondent met the statutory requirements to be declared an adult interdependent partner. The appellant challenged the interpretation of living together under s. 3(1)(a) of AIRA, the sufficiency of corroborating evidence, and the finding that the parties functioned as an economic and domestic unit....
