Hon. L. S. ST. LAURENT (Acting Secretary of State for External Affairs): Mr. Speaker, I wish to table some notes recently exchanged between the governments of the United States and Canada with respect to diversion of water at Niagara for power purposes, and to make a short explanation to the house with regard to the present state of Niagara diversion arrangements.
Notes between the Canadian government and the government of the United States were exchanged at Washington as of May 3, to provide for an additional diversion of 4,000 cubic feet per second of water at Niagara for power purposes. Prior arrangements providing for the production of additional hydroelectric energy at Niagara for war purposes are embodied in a series of agreements which were evidenced by exchanges of notes.
The earlier notes thus exchanged were tabled in this house from time to time. All these increased diversions of water are subject to reconsideration on the first day of October in each year. The previous arrangements also provided for the construction of remedial works. Accordingly the United States-St. Lawrence advisory committee and the Canadian temporary Great Lakes-St. Lawrence basin committee prepared recommendations, which were approved by both governments, regarding the exact nature and design of the remedial works.
The Canadian government arranged with the Hydro-Electric Power Commission of Ontario for the latter to do the actual construction work, and it is now nearing completion. It has been even more effective than had been expected, both in adding to the efficiency of the power developments and in preserving and improving the scenic beauty of the falls. The new exchange provides that this additional diversion, for power purposes, of 4,000 cubic feet per second shall be made on the Canadian side of the Niagara river. Most of the additional energy will however become available for use in the United States. There is no new question of export of power involved, as this additional electrical energy will come under the provisions of the previous arrangements.
The new diversion arises out of a request from the United States government, but, as the diversion is on the Canadian side, the ar-
rangement takes the form of a note from the Canadian Ambassador to the Secretary of State and a reply constituting an agreement.
Copies of the notes exchanged in English and in French are now tabled for the information of the members of the house.
