In the 19th century, the Toronto Police mostly focused on the suppression of rebellion in the city—particularly during the Fenian threats of 1860 to 1870. The Toronto Police were probably Canada's first security intelligence agency when they established a network of spies and informants throughout Canada West in 1864 to combat US Army recruiting agents attempting to induce British Army soldiers stationed in Canada to desert to serve in the Union Army in the Civil War. The Toronto Police operatives later turned to spying on the activities of the Fenians and filed reports to the Chief Constable from as far as Buffalo, Detroit, Chicago and New York City. When in December 1864, the Canada West secret frontier police was established under Stipendiary Magistrate Gilbert McMicken, some of the Toronto Police agents were reassigned to this new agency.
