That is true, except that one might argue that ultimately the Canadian shareholders of that company could benefit if there is expansion of that corporation internationally. There could be potentially some benefit there, at least to a Canadian shareholder of that corporation, whereas if it's foreign owned, there is none.
Si cette filiale canadienne a des dettes, même envers sa société-mère, puis investit à l'étranger et déduit des frais d'intérêts au Canada, eh bien, au bout du compte, les bénéfices ne reviennent pas au Canada.
