Immediately after the war was declared economists, and many others, became concerned with how the war would affect the Canadian market. By 6 August, there was already a price increase in sugar and flour, which were two of the main necessities of Canadian homes. It was also predicted that the prices of other foodstuff and clothing would increase in the near future.
On 6 August, the Berlin Daily Telegraph reported that Mr. J. Uffelman, of the Ontario Seed Company, stated that while the war would not affect the 1914 harvest, next year’s harvest might be affected. This was because the war might potentially prevent the importation of certain varieties of seeds, especially those that were normally imported from Germany. This would affect the Waterloo Region, where some farmers grew a European variety of rye.
