Salt v. The Queen, 2007 DTC 520, 2007 TCC 118 -- summary under Article 4

The taxpayer, when he was moved by his employer to Australia rented the Canadian home of him and his wife under 22 1/2 month lease which, under Quebec law, was not terminable other than on six months notice, and was provided with a furnished house in Australia. In these circumstances, the Canadian house was not a permanent home available to him under Article 4 of the Canada-Australia Income Tax Convention, so that he was resident in Canada for purposes of that Treaty and for purposes of the Act by virtue of s. 250(5).
