In interpreting s. 42 of the Special Import Measures Act (Canada), it was proper for the Canadian Import Tribunal to consult the terms of the GATT Subsidies Code. Gonthier J. stated (p. 1371):
"It is reasonable to make reference to an international agreement at the very outset of the enquiry to determine if there is any ambiguity, even latent, in the domestic legislation. The Court of Appeal's suggestion that recourse to an international treaty is only available where the provision of the domestic legislation is ambiguous on its face is to be rejected."
