CANADA ALLOWS PUBLISHING TAKEOVER BY HARCOURT Investment Canada said it has allowed the indirect takeover of Holt, Rinehart and Winston Canada Ltd., W.B. Saunders Co of Canada Ltd and Les Editions HRW Ltd by Harcourt Brace Jovanovich Canada Inc. The government agency said, however, Harcourt Canada has agreed to sell control of the firms to Canadian interests within two years. Harcourt Canada's U.S. parent, Harcourt Brace Jovanovich Inc <HBJ>, indirectly acquired the Canadian book publishing companies when it purchased Holt Rinehart and Winston from CBS Inc <CBS> last October.
