The county was established on March 7, 1891, with its county seat at Caldwell. It was partitioned from Ada County and originally included Payette County (1917) and the southern portion of Gem County (1915). Current sources attribute the name to the canyon of the Boise River near Caldwell. However, both John Rees and Vardis Fisher believed it was named for the Snake River canyon which forms a natural boundary for the county with Owyhee County. The Hudson's Bay Company established Fort Boise in 1834 near what is now Parma, but abandoned it in 1855. Emigrants traveled through Canyon County on the Oregon Trail.[3] The Oregon Short Line Railroad was completed in 1883.
According to the 2000 census, the county has a total area of 603.51 square miles (1,563.1 km2), of which 589.72 square miles (1,527.4 km2) (or 97.72%) is land and 13.79 square miles (35.7 km2) (or 2.28%) is water.[4]
