that, in the latter part of 1917, more than half of the shrapnel shells used by the British army in France and Flanders were made in Canada.
By the end of February, igi8, some 500 factories, employing over a quarter of a million work-people, were making shells and cartridges, preparing other special war materials, and building ships to replace those destroyed by the submarines.

But year by year Canada's mines have become a greater source of wealth. For instance, in 1916 the products of the mines were worth over seventeen times what they were valued at, thirty years before, in 1886.
