The C of G was a mounted corps of Non-Permanent Active Militia with precedence immediately following the Canadian Engineers. The officers, non-commissioned officers (NCOs), and men were appointed individually to the headquarters staffs of various commands and districts to carry out Intelligence duties. From the authorizing order, it is apparent that one of the functions of the C of G was to ensure that, in the event of war on Canadian soil, the defenders would possess detailed and accurate information of the area of operations. The ranks of the C of G were filled quickly, and by the end of 1903, the general officer commanding the militia was able to report that, "the formation of the Corps has been attended by the best possible results. Canada is now being covered by a network of Intelligence and capable men, who will be of great service to the country in collecting information of a military character and in fitting themselves to act as guides in their own districts to forces in the field. I have much satisfaction in stating that there is much competition among the best men in the country for admission into the Corps of Guides. Nobody is admitted into the Corps unless he is a man whose services are likely to be of real use to the country."
