After noting that the interpretation advanced by the taxpayer had the effect of making a statutory definition of "hedging" redundant (as such interpretation had the effect of limiting the taxpayer's mining profits to the consideration actually received from sales of its production, which would have been the case even without their purported expansion to hedging profits), LeBel J. stated (at para. 45):
"Under the presumption against tautology 'every word in a statute is presumed to make sense and to have a specific role to play in advancing the legislative purpose' ... . To the extent that it is possible to do so, court should avoid adopting interpretations that render any portion of a statute meaningless or redundant ...".
