ACCORDING to the report of the Ontario Research Foundation for the year 1943, that year saw a peak in the activities of the Foundation; for the first time since 1928 the problem of allotting laboratory space became acute. Some decision as to whether increased or permanent extensions are justified will be required in the near future. A second limiting factor has been the supply of trained research workers; until the demands from military departments and the war industries diminish, it will be impossible to devote adequate and sustained attention to post-war problems. The transition period might be shortened ii research relating to post-war problems were given a higher rating in the system of controls and restrictions. It was not until shortly before the present War that any considerable use was made of the Foundation's facilities other than for routine services and short-term investigations, and at present the Foundation cannot establish enough fellowships to take care of the demand for research. This change is largely due to the gradual development and diffusion of a correct understanding of the relation between, industrial scientific, research and economic stability. It would add greatly to the stability and continuity of scientific research if the Governments concerned would encourage and not disallow the establishment of reserves for research.
