The Supreme Court unanimously held that the provisions cited in Question 1 were
ultra vires the Parliament of Canada, as
fish canning only occurs after the fish have been caught, thus not being within the federal fisheries jurisdiction. As a fish cannery is similar in nature to a fruit or vegetable cannery, it is a civil right in the province in which it is carried on, and therefore subject to provincial jurisdiction. Nor could such provisions be saved by resorting to another head of power: It was unnecessary to answer Question 2. In a 4-3 decision concerning Question 3, it was held that the Minister must issue fishing licenses to all qualified persons that paid the appropriate fee, and there was no discretionary authority to withhold such licenses.
Newcombe J (
Anglin CJ and
Rinfret and
Lamont JJ, concurring) stated that the Minister could not exercise his licensing discretion in a discriminatory manner:
Duff J (
Mignault and
Smith JJ, concurring) believed that "There is nothing in the terms in which these provisions are expressed, nor, as far as I have been able to discover, in the terms of the regulations, pointing to a conclusion that the authority of the Minister is not a permissive one." The federal government chose to ignore the ruling, pending appeal to the Privy Council. In the interim, prosecutions against Japanese-Canadian fishermen were being dismissed in the lower courts. The Association of Fishermen of Japanese Origin, having intervened in the hearing at the Supreme Court, were also respondents in the appeal. ==At the Privy Council==
