The taxpayer, which was a resident of the U.K. and carried on an international shipping business both directly and through subsidiaries, provided various services through its Canadian branch office in respect of both its own ships and those of subsidiaries, including the provision of stevedoring services, the finding and booking of cargo for the ships and attending and participating in rate setting and other activities of the Canada-U.K. Eastbound Freight Conference. In finding that the profits attributable to these services provided in relation to the taxpayer's own ships came within the exemption in s. 10(1)(c) of the pre-1972 Act for "income for the year of a non-resident person earned in Canada from the operation of a ship or aircraft owned or operated him", Thurlow J. stated (p. 5366):
"Both the 'agency' and stevedoring services in respect of which the entries arose were part of the process of operating the ships and the amounts entered in the books in respect of such services do not become any the less exempt by reason of the manner in which the appellant organized the activities of its branches or arranged their bookkeeping and accounting."
However, no similar exemption applied to such services provided to subsidiaries.
