In finding that reference to control by a person did not include control by persons, Cartwright J. stated (pp. 1192-1193):
"When section 127 by clause (b) provides that corporations controlled directly or indirectly by the same person shall be deemed not to deal with each other at arm's length it appears to me to negative the view that corporations are to be deemed not to deal with each other at arm's length when controlled not by the same person but by the same group of persons. Expressio unius exclusio alterius. When the wording of clause (b) of section 127 is contrasted with that of clause (a) it seems to me impossible to read the word 'person' in clause (b) as including the plural".
